Hello... My name is Roberto Fresca, and I'm part of the MAME Dev Team since 1998. Here you can find some technical things about rare hardware. This site is intended to avoid duplicated efforts.
This page is still in construction...
Special thanks to mameworld staff, that offered me to host this humble page.

A couple of weeks ago, I started a new driver with Grull Osgo for a very rare IGS platform.
The involved game is "Five Clown", and is running in a dual 6502 CPU + AY8910 + OKIM6295 system. Main program, graphics and sound samples are encrypted.
Fortunately, I managed to get the proper decryption algorithm for each part. The sound system is tied to quad and octal-latch IC's, so is not mapped to the CPU directly...
Except for some sound related misterious writes, that need to be figured out, the game is working properly. Here some snaps:
Five Clown (IGS):
The driver is quite complete. Still need to trace code for some DIP switches, and solve these misterious writes...

Thanks to Team Europe that found a new board, I managed to fix graphics and colors of Impera's Jolly Joker.
Obviously, a new set was added to the family. Here some snaps:
Jolly Joker (Impera).
There are more remaining things from Team Europe. Soon will get some news about them...
--- 2010/02/07 00:45 ---
I started to write a driver for Sigma B52 system. This platform is a complex gaming system based on 2x M6809 CPU's, 1x YM3812 sound device, and a very complex video controller (H63484 ACRTC). Thanks to Tomasz Slanina that kindly joined efforts hooking the ACRTC stuff, and Fabio Priuli converting this controller to a device.
The ACRTC implementation is a bit hacky due to its preliminary emulation state. Here are some snaps:
Joker's Wild (B52).
And now, some snaps from a new game dumped by Team Europe: Treasure Island from Subsino. We're working with Angelo Salese and David Haywood to get it working...
Colors are wrong due to undumped bipolar PROMs.
--- 2009/10/24 21:45 ---
Thanks to Darklord & Team Europe, that kindly dumped the PCB, a new enhaced version of New Lucky 8 Lines appeared.
This set has a regular New Lucky 8 Lines game, but allowing bets up to 64. It has different settings/parameters, and additional graphics for a game called New Super 8 Lines. There are basic reels tiles with a semi-naked woman, a sort of Super Mario character from Nintendo, clouds and stars...
Still can't find how to switch between games. Here are some snaps:
New Lucky 8 Lines / New Super 8 Lines.
And here the extra tiles arranged...
In other news, I added a japanese set of Draw Poker Hi-Lo and a SMS poker also with Hi-Lo features.
--- 2009/09/03 03:45 ---
Thanks to Team Europe, that kindly dumped the PCB, one of the older Cal Omega videopokers from system 903 is now emulated. A new set of inputs were worked from the scratch to get it happy.
The game is currently working, with full sound. Payout is manual. Here are some snaps:
Cal Omega - Game 7.4 (Gaming Poker, W.Export).
In other news, I passed all the Noraut System VRAM handlers through PPI8255-2. This device is configured in a unusual mixed mode: Mode2 for group A (full bidirectional port with 5-handshaked lines) + Mode0 for group B out (regular port out lines) + some C lines as I/O. Unfortunatelly need to bypass/hack the OBF handshake line because it's not working as expected. Otherwise all games are entering in an infinite loop.
--- 2009/08/29 20:40 ---
This time I worked to document every I/O port. As consequence, some inputs were changed, lights were hooked, and the two existent control panel layouts were added.
Also fixed some other stuff. Here are some snaps:
Noraut Joker Poker.
Noraut Red Hot Joker Poker.
--- 2009/08/26 00:40 ---
We were made some experiments. I made a trojan that Alan Griffin kindly ran in his system. That was great to confirm how the 16x32 tiles are decoded/arranged. Even confirmed that colors are 100% accurate.
New improvements were made. The screen aspect and visible area were fixed, x-axis offset of 32x32 tiles was corrected, added a default NVRAM to Noraut Joker Poker to avoid the phisical keyboard limitation regarding multiple simultaneous inputs. Here are some snaps:
Noraut Red Hot Joker Poker.

Well... Back from Helsinki. I've received an invitation as symposium speaker at Assembly'09, discussing about emulation and talk about my own experience. I'll post something more about this experience soon.
Regarding emulation, I made a lot of improvements to Noraut Poker driver. Also added some new sets dumped by Alan Griffin. Sound is discrete and need the real circuitry traced to be implemented. Here are some snaps:
Noraut Red Hot Joker Poker.
Here the changes:
- Switched to pre-defined Xtal clock.
- Changed the way how graphics are banked/accessed.
- Fixed the graphics offset and number of tiles per bank.
- Added new set: Noraut Red Hot Joker Poker.
- Added new set: Noraut Poker (NTX10A).
- Added new set: Noraut Joker Poker (V3.010a).
- Fixed the tile size/decode for the first GFX bank.
- Added proper norautrh inputs, including the readout button.
- Added partial DIP switches to norautrh.
- Added more technical notes.
--- 2009/07/20 03:20 ---
Well... I was very busy trying to solve big troubles in RL(tm). Last days I started to move a bit regarding emulation...
This time I made a lot of improvements to Merit Multi-Poker. All the 4 games are working, but unfortunately the color is still wrong. Sound seems to be discrete and need the real circuitery traced to implement something. Here are some snaps:
Merit Multi-Poker.
'Pharaohs' game.
'Wild Bulls' game.
'The White Knight' game.
'The Frog Pond' game.
Here the changes:
- Full Inputs.
- DIP Switches.
- Simulated spark-watchdog circuitery.
- Demuxed custom port.
- NVRAM support.
- CPU clock derived from #defined crystal.
- 8000-8007 Output ports.
- Coin related counters.
- Sound components and trigger found at 8000-8003, bit2.
- Full lamps support.
- PCBs layouts & technical notes.

I really love when we start something about a rare game, knowing nothing about the hardware or the game itself, and we get the game working with all bells and whistles...
This time I worked with Angelo Salese and Tomasz Slanina, and got this rare keno game working. Here are some snaps:
Big 10.
--- 2009/01/11 09:30 ---
There are some assorted news regarding the Cherry Master type machines. First, I've fixed the color decode of Cherry Master and Lucky 8 Lines types. See the before-after pics:
Also I did a lot of work and some new additions... Here are some snaps:
Kkoj Noli (south korean hack... It means "Kill the Bees").
Cherry Master '91 (now working, with all the inputs/DIPs and fixed reels colors).
Also added a weird version of Cherry Master. The game is hidden into a Tetris game. Seems to be designed for locations or countries where gambling games are/were not allowed. The owner swear that the game boots in Tetris mode, but I got it booting in Cherry Master mode. Even when the gambling part is properly emulated, I flagged the game as not working till can figure out how to switch between games. Thanks to Kale that fixed the rom banking.
Haze decoded the extra gfx bank for some Cherry Master sets that have the girls graphics in a different bitmap format, stored in an extra ROM. Still not figured out how the game use it.
And for last (and no least), We have both cm2v841 and cm2841a sets working. Just renamed as cmasterb and cmasterc respectively
since they are different sets of Cherry Master I (ver.1.01).
--- 2009/01/06 08:00 ---
I started a driver for this one long time ago... Now I merged it with the Wing/Dyna stuff and improved the emulation. A lot of work involved in memory maps, I/O devices, inputs, colors, etc... The game is working properly with full sounds. Here are some snaps:
Lady Liner (TAB Austria).
--- 2009/01/04 12:30 ---
Soon MAME 0.129 will be released. I teamed with Haze to get the following games working: Cherry Master I (v.1.01), Cherry Master (Corsica, v.8.01) and Cherry Master (v.4). Here are some snaps...
Cherry Master I (v.1.01)...
Cherry Master (Corsica, v.8.01)...
And Cherry Master V4...
Also we wrote a new driver to support Slot Carnival (1985, Wing Co, Ltd). The driver is quite complete, but still need a lot of work on the complex video hardware to proper support reels and accurate colors. Not working, yet
As usual with these kind of games, a lot of work on PPI devices, inputs, DIP switches, NVRAM, etc...
--- 2008/12/31 02:30 ---
Well... After a hard work, I was able to finish the New Lucky 8 Lines emulation. Lot of work on PPI devices, inputs, DIP switches, NVRAM, etc...
Haze made a very good job fixing the colors.
And 2 different kind of Double-Up: Automatic (reels) or player select (cards)...
Also got Cherry Gold I and Cherry Bonus III working properly (same mess). Some new dumps were added. Andreas Naive (a brillant mind), decrypted the encrypted set...
All the above (except Cherry Gold I) have a 2nd set of controls that can be switched through the 'BIG' button. BTW, all are full working with sound... Have a Happy New Year!!!
--- 2008/12/04 00:30 ---
We're so close of u5. Here are the following new additions...
Thanks to Guru, that kindly dumped an original Witch Card board from Video Klein (and a scary epoxy CPU/program/protection block), we have it running now as the parent set. The game is not working yet due to protection. An unknown 40-pin IC inside the big epoxy block is acting as a MCU. I strongly think is another PIA mapped at $2108-$210b. Hope Guru can trace the IC connections to have an attempt to ID this mysterious device. As soon as you insert a credit, there are some writes and reads to the IC and the program flow goes to the hell...
Witch Card (Video Klein)...
Maverik... Yes, withouth a "c". ;-)
Brasil'89... Another common D-UP poker.
Poker 91. This one is different. It has switch keys instead of hold keys. You must bet on each card to switch. Also the D-UP feature is similar to the one present in Witch Card, giving big numbers and act as a slots game.
Want more?... There are 22 Buena Suerte sets in the upcoming 0.128u5...
--- 2008/11/01 00:30 ---
Due to Halloween, I need to post the following improvements...
After a hard analysis, the Witch Card hardware emulation was improved. Now the double-up feature and the witch game are working!...
Each time you win a double-up, a little witch with a big number inside is added (maximum 3). When you lose/take credits, a kind of slots game starts. The witches numbers start to run and you have some attempts to win an extra bonus. However, only the spanish sets are full working. The english set was brute hacked to always lose the double-up and avoid the witch game. So sad...
Also the Super Loco 93 sets now have double-up and a particular bonus game working properly...
What more?.... The Jack Potten's poker sets now have their own double-up game working properly too...
The driver is still under developement. New games/clones will be added soon and need an exhaustive analysis to determine a new set order. Please be patient.
Oh... I forgot!. The RE-900 external artwork was improved. See the following panel detail.
Before...
After...
Now it looks more realistic!...
--- 2008/10/31 ---
We have some things for the upcoming beta...
Another driver from Grull Osgo, finished/polished together: Ruleta RE-900 from Entretenimientos GEMINIS. The hardware is based on a P80C31 as CPU + AY-8910 for sound + TMS-9129 for video, and use a plastic roulette-replica as device. The ball is simulated through an array of lamps inserted in the plate. The game allow up to 6 players and is working like a charm... We also made a good external artwork to feel the real thing... ;-)
Also we found a Buena Suerte version called "Buena Suerte '94" running on the same hardware. Veeeery rare...
Something more....
- Added Sigma-Delta DAC sound support to Magic Fly and 7 e Mezzo.
- Hooked coin counters to both games.
--- 2008/10/12 ---
Since several weeks ago I'm working in pmpoker.c driver again. A ton of things were changed/improved, so I'm rewritting the whole thing in some steps. One of the most expected improvements is
the DISCRETE SOUND SUPPORT for ALL games. Now we can enjoy the farty sounds of games like Golden Poker Double Up and Jack Potten's Poker.
Also there are new upcoming games. Some of them are veeeery rare. Here some snaps...
Witch Card... One of the most wanted. There are 12 unknown parameters to setup the game. Still can't get the Witch Game bonus round...
Super Loco 93... An addictive 3-cards game. Very rare.
Buena Suerte!... Argentine reprogrammed version of Golden Poker. Running on Witch Card hardware.
And yes... The background is BLACK! ;-)

Whilst working on the 'Scacco Matto / Space Win' game, Haze pointed me that the Playmark Roulette needs it MCU simulated in order to work (in fact, the protection turns the game to 'always win'), so I took a look at the driver and started the tedious work.
As result, the MCU has been simulated and you now can play a normal game, but is a bit hard to win. I don't know if it's so accurate, but is a step further till we have the MCU decapped (if it's possible).
In the next couple of pictures, you can see the number 4 (four) as winner number, and all the bets were placed around number 20 (twenty). So... You now can lose! ;-)
Also I made a lot of things on this driver.... Some of them are: added full music/sound support to the roulette, fixed the phisical RAM size, added proper NVRAM and lamp support to all games (sderby, spacewin & pmroulet).
--- 2008/09/05 ---
Just turned out an obsession... As soon as I saw this game, I put a lot of work to emulate it. All things (planes, tilemap offsets, protection, NVRAM, sound, inputs, DIP switches, etc..) are perfectly emulated, except the hopper and ticket dispenser. Also not only was added button-lamps support. I've improved the layout to represent lamps in a way more realistic. The final look is quite impressive due to the good lamps sequence the game already has.
NOTE: To initialize the game, you must left DIP switches in default position, and enter the following sequence: HOLD4, HOLD2, HOLD5, START. A lot of thanks to Tomasz Slanina that helped me fixing interrupts and finding the init sequence. Here some shots of the game running...
Here the Super Game feature... The player must hit the lion to get the price. For now you must to miss the shot till hopper and ticket dispenser are emulated. ;-)
--- 2008/08/30 ---
I'm absolutely sure that some people will be happy to see this sympathetic character again... ;-)
Well... The game is NOT "Carta Magica", as some people expects. This one is Magic Joker, recently dumped by f205v. It seems to be a clone of, hack of, or simply stolen some graphics from Carta Magica. Here some shots of the game working...
Each time you win a hand, the game plays the song 'La Cucaracha'... Nice and addictive. :-)

InterFlip is a spanish company that manufactured/exported pinballs and class 'C' (casino) games. The hardware is composed by two (main and sound) boards driven by a I8039 each. The video and color RAM are addressed through I/O ports and latch tricks due to the I8039 addressing restrictions. The work is mostly from Grull Osgo, and after a lot of work we have all games working properly with sound. Here some shots...
Video Poker:
Black Jack:
Video Dado:
Video Cordoba (still needs its own color PROM):

After some analysis, the co-processor calls were identified. Once simulated the behaviour, the co-processor test was passed ok. The next problem I've found was the input test, that didn't pass at all. After program all the inputs from the scratch, the test was passed successfuly.
Tilemap layers now are aligned, and a preliminary scroll register support was added (needed to align the 3rd graphics layer in different parts of the game). Unfortunatelly the game resets due to protection issues...
Here some shots...
Also I fixed the Super Pool graphics:
Before...
After...
--- 2008/08/08 ---
Well... A lot of improvements to the driver were made. The color system now is based on the resistors weights, interrupts were measured and fixed, and much more... Also a week ago, we (with Grull Osgo) got the regular sounds working after implement the missing 3x SN76489.
Respect to the custom IC's, we almost finish the reverse engineering. The samples system (09R81P + OKI M5205) is now implemented and working properly. Now Lucky 74 can talk!...
Here the custom IC's...
06B49P: This IC is a programmable clock divisor. It provides every frequency needed for all devices from this hardware, plus V-Sync, H-Sync and (V+H)-Sync (composite) frequencies. All generated clocks are proportional to the Clock In (12MHz). There are not fixed or harcoded frequencies.
06B53P: This IC is a custom video controller. The PCB has two of them. Each one handle one graphics bank, the respective video (and color) RAM, and switch the dual-state color circuitry to generate its own palette.
09R81P: This custom IC is a kind of samples system controller, driving the OKI M5205. The IC is connected to Z80 through ports 0x00 to 0x05. Transmit the status (/busy) to port 0x00 (bit 0). Load the sample start offset from ports 0x00 & 0x01 and the ending offset from ports 0x03 & 0x04, then trigger the sample when the bit 0 of port 0x05 is activated.
More to come...
--- 2008/08/04 ---
At very begining, I thought that both games were candidates for the 'only-for-preservation-skeleton-driver' due to the fact that the main CPU was meant to be a Hitachi/Remesas MCU with internal ROM.
Then, Surprisingly... I found valid M68000 code in a couple of ROMs :))). The attract of Magic Colors is working but the game is not playable due to protection issues, and Hot Slot is not working due to the lack of co-processor emulation. Here are some shots...
Hot Slot... To pass the System RAM test, bit 7 at offset 0x500005 should be activated. The test fails in the co-processor item due to the lack of co-processor emulation.
--- 2008/07/06 ---
The game is now playable... Anyway, still need a lot of work (sound, copro, resnet, etc...). Here are some comparative shots...
And the next stage, with less clothes...
And one stage more, with less clothes than before...
...And stop here to preserve my account! ;-)
Next step is to switch the dual-state color system to RESNET...
--- 2008/07/04 ---
Well... I spent a lot of time working on this one. Manufactured by Wing Co. Ltd, Lucky 74 was a kind of legend at least on this side of the world.
The hardware looks interesting: A black CPU box based on Z80, NPC SM7831 co-processor, 2x 82C255 (equivalent to 4x 8255) for I/O, a YM-2149F
and OKI M5205 for sound, and a USART IC for serial/parallel communication. The color circuitry is based on different states and assign
a different palette for each graphics bank. Two video RAMs handling fore & background graphics respectively that will be merged
in the final blitter. In fact, the game is very addictive and has good whores graphics.
Only the attract mode is working for now, and sound need to be hooked/fixed. A lot of thanks to Tomasz Slanina, that fixed the lack of interrupts at very begining, and Grull Osgo, that provided a complete dump, PCB pictures, bipolar PROMs connection info, and then vanished in the ether... (maybe the known curse of this game reached him). Here some shots...
--- 2008/06/01 ---
Reworked the Sigma 2000 inputs. After the init sequence, the game started to work properly. In fact it has good graphics and adictive gameplay.
--- 2008/05/21 ---
Some shots of Super Pool running. The game isn't working properly due to protection.
*** Blue TAB PCB decryption ***
I finally found the proper algorithm to decrypt the blue TAB PCB games.
To all people that asked about, the board performs by byte nibble a boolean XOR against the same value shifted to the right, then shift the result to the left carring the less significant bit and losing the most significant one.
Encrypted value: 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1111
------------------------------------------------------------------------------------------------
Decrypted value: 0000 0011 0110 0101 1100 1111 1010 1001 1000 1011 1110 1101 0100 0111 0010 0001
So we performed the following calc:
decrypted_byte = ((X ^ (X >> 1)) << 1 ) + (((Y ^ (Y >> 1)) >> 3) & 0x0f)
Being X & Y the encrypted nibbles...
The old decryption tables were replaced with the proper decryption scheme in release .125u1. Another hack gone... :-)
--- 2008/05/12 ---
Well... These are 2 different games running in the same platform. A multi card game (Draw Poker, Stud Poker, Acey-Deucy, Blackjack and High-Low) where you can choose the game to play, and a slots thematic game where you can play choosing a 'ticket'. Both games are working properly, but without sound (the sound device wasn't identified due to almost all ICs are plastic-covered).
I have NO IDEA about their real names. If you have some reference or know something about them and want to help, please contact us through the MAMEDev Contact Form, or post something in the MAMEWorld Forums.
Card Games?? (Game-A-Tron, 1983).
Slots Game?? (Game-A-Tron, 1983).

After playing for a couple of days with graphics bitplanes, boolean operations and bitswaps, I was able to fully decrypt the Apple 10 color codes. Here some shots...
Apple 10 in game, plus stats, management, input test & programming modes.
BTW, Hooked full sound emulation to all games. The sounds are 4 bit ADPCM and were ripped from the Gottlieb pinball 'Cue Ball Wizard'(1992)...
Output ports were hooked and properly documented too.
**** Edited ****
Also fixed the payout mode.
If you have some points accumulated and need to grab the tokens/tickets, you must to play a bonus game called SUPER GAME to get the points out. To enter the bonus game, you must press STOP5 in the attract mode. The payout system is through this game.
5 themed items will be shown (apples, balls, etc... depending of the game). The joker will start to move from item to item quickly, but decreasing the speed gradually. To beat the game, you need to push the start button in the exact moment when the joker is located exactly in the center of the screen (item 3).
Depending of the DIP switches settings, you can grab the prize manually pressing the SCARICA (payout) button, and then TICKET or HOPPER buttons. Press TICKET button to print a 100 points ticket. Press HOPPER button to get tokens x10 points.
You have 1 attempt for each 100 earned points. If you lose the game, you lose the points.
And since this feature is present in all the CMC italian games too, I made a lot of fixes to them to allow work the payout system properly.
--- 2008/04/26 ---
Well... After some work, I have Snooker 10, Ten Balls and Apple 10 working. The last one still need a big analysis to decrypt the palette properly. Here some shots...
Snooker 10 in game, plus stats, management, input test & programming modes.
Apple 10 in game...
The next step is to hook sound emulation and document the output ports properly.
--- 2008/04/23 ---
I was busy trying to decrypt/unscramble the tile matrix of Apple 10.
Once tiles were decoded, you can see the following table, where 'norm. tile#' is the tile number called to be drawn and
'scrambled tile#' is the phisical tile position in the matrix:
Norm.| Scrambled
tile#| tile#
-----+--------
0x00 | 0x00 \
0x01 | 0x80 |
0x02 | 0x40 | Big "0"
0x03 | 0xC0 |
0x04 | 0x20 |
0x05 | 0xA0 /
-----+--------
0x06 | 0x60 \
0x07 | 0xE0 |
0x08 | 0x10 | Big "1"
0x09 | 0x90 |
0x0A | 0x50 |
0x0B | 0xD0 /
-----+--------
0x0C | 0x30 \
0x0D | 0xB0 |
0x0E | 0x70 | Big "2"
0x0F | 0xF0 |
0x10 | 0x08 |
0x11 | 0x88 /
-----+--------
So we extract the following decrypt table:
0 <-> 0; 1 <-> 8; 2 <-> 4; 3 <-> C
4 <-> 2; 5 <-> A; 6 <-> 6; 7 <-> E
8 <-> 1; 9 <-> 9; A <-> 5; B <-> D
C <-> 3; D <-> B; E <-> 7; F <-> F
...and then swap nibbles.
Note that the values are inverted/mirrored bits.
0x01 (0001) <-> 0x08 (1000)
0x02 (0010) <-> 0x04 (0100)
0x03 (0011) <-> 0x0C (1100)
0x04 (0100) <-> 0x04 (0010)
0x05 (0101) <-> 0x0A (1010)
...and so on.
To properly decrypt the thing 'on the fly' as the hardware does, I applied a bitswap. Here the results...
Tiles are ok now. The next step is to tackle the color system...
**** Edited ****
Well... Colors are scrambled in the following way:
..Normal..| Scrambled
..offset..| offset
----------+-------------
0x00-0x0F | 0x00-0x0F
0x10-0x1F | 0x80-0x8F
0x20-0x2F | 0x40-0x4F
0x30-0x3F | 0xC0-0xCF
0x40-0x4F | 0x20-0x2F
0x50-0x5F | 0xA0-0xAF
0x60-0x6F | 0x60-0x6F
0x70-0x7F | 0xE0-0xEF
----------+-------------
0x80-0x8F | 0x10-0x1F
0x90-0x9F | 0x90-0x9F
0xA0-0xAF | 0x50-0x5F
0xB0-0xBF | 0xD0-0xDF
0xC0-0xCF | 0x30-0x3F
0xD0-0xDF | 0xB0-0xBF
0xE0-0xEF | 0x70-0x7F
0xF0-0xFF | 0xF0-0xFF
So I made a slightly different thing, based on the same algorithm. Here the results...
Most of colors are correct. Still need to analyze the few wrong color codes...

Another 2 italian games were dumped (thanks f205v!). I made a new driver for them. They are Apple 10 and Ten Balls. Both programs seems to be heavy hacks from funworld games. Obviously all hardware accesses were relocated to match the new hardware, that has two big high-density PLDs mainly for protection. Also moved Snooker 10 to this new driver. All games aren't working yet. Here some shots...
Ten Balls, from an early revision board.
Apple 10. This one has colors and tile matrix encrypted/scrambled...
Decryption is a real PITA...
I think I'm on the right way, but still have no idea how to implement it. Stay tuned... ;)
--- 2008/03/18 ---
Thanks to f205v and Stekka51, another italian game was dumped. The game follow the line of C.M.C. games (video poker with different graphics due to legal issues). The game is working properly with sound. Here some shots...
The game will be part of the next beta.
--- 2008/02/27 ---
This is Cal Omega - Game 10.7 (Big Game). The game need a keyboard attached to the PCB through a keyboard encoder. The emulation state is still preliminary...
Last night I submitted the new Cal Omega monster (still preliminary), so it will be part of the next beta.
--- 2008/02/25 ---
Thanks to Aleksandar Spasojevic that kindly dumped some boards, a bunch of new games were added. I also fixed some inputs and mask others to allow boot the original Impera Jolly Joker (unfortunately 1 graphics ROM is bad). The color decode system was switched to resnet code, so colors are now more accurate. Here are some shots...
Jolly Card (Evona Electronic). This version is in serbian language.
Jolly Joker (Impera). One of the wanted dumps. Unfortunately 1 ROM is bad...
Super Joly 2000 -3x. This one have a 3rd deal, hacked graphics (see the Magic Card II joker) and advertisement about sell parts and technical service. Ugly hack, but was common in the serbian streets.
--- 2008/02/10 ---
Even when I'm short of spare time, I made some progress with all the Funworld stuff. Lots of changes to the driver and some new additions. Here are some shots...
Jolly Card (3x3 deal). This version allow the player to get a 3rd deal.
Jolly Card Professional 2.0, from Spale-Soft. This version generate a code each 1st boot. You need an external PC program to enter this code and get the needed inputs sequence to boot the game.
Lucky Lady (3x3 deal). Another 3-deal game, heavily based on Royal Card.
Lucky Lady (4x1 aces). Same game as above, but with other features instead.
Royal Vegas Joker Card (slow deal). A different poker game from Funworld.
Royal Vegas Joker Card (fast deal). Clone of above with 'fast deal', from Soft Design. I didn't play it enough to see the differences.
And here the complete list of changes...
- Switched to XTAL def.
- Fixed Magic Card II graphics issues.
- Fixed Magic Card II inputs.
- Fixed screen and visible area to snooker10.
- Renamed set monglfir to mongolnw.
- Renamed sets description based on languages instead of countries.
- Added new game: Magic Card II (green TAB or Impera board). Not working yet.
- Added new game: Magic Card II (blue TAB board, encrypted). Not working yet.
- Added new game: Jolly Card (3x3 deal).
- Added new game: Jolly Card Professional 2.0 (with 'enter code' screen to boot).
- Added new game: Lucky Lady (3x3 deal).
- Added new game: Lucky Lady (4x1 aces).
- Added new game: Royal Vegas Joker Card (fast deal).
- Added new game: Royal Vegas Joker Card (slow deal).
- Fixed some years and manufacturers.
- Updated technical notes.
- Cleaned up the driver.

Well... Really are old news due to my lack of spare time. I solved this puzzle a week ago. A collaborator sent me some encrypted Magic Card ROMs and after decrypt them, I was able to see what's wrong with the current dump. Here are some shots...
Magic Card (Impera)
More SOON!
--- 2007/12/24 ---
Well... One item of my 'todo list' is to reconstruct the gdrawpkr driver to support Cal Omega systems 903, 904, 905 and 906. I'm really very busy with my new job, but I started the big change. An external collaborator sent some dumps (some are messy, bitrotten, bad dumps) and an official list of games. This list is not complete, but I'm adding the missing entries. There are 114 games in the list ATM. Most games aren't working due to hardware differences and/or input/output problems. Here are some shots...
Poker (amusement) v7.6
Keno (amusement) v9.4
SSI Poker 2.4
SSI Poker 3.0
Pixels v14.5
Double-Draw Poker v15.7
Wild Double-Up v15.9
Super Blackjack v20.4
Hotline v24.6
Jackpot Joker Poker
Merry Christmas and Happy new year!

Fixed Sigma Poker 2000 graphics (cards deck). Changed a lot things. The game has improved graphics and use 4 times more tiles than other games running on this hardware. To handle this, the game use 2 extra bits from the color RAM...
The game is still not working.
--- 2007/11/13 ---
Well... This is Sigma Poker running in a modified American Poker II hardware. The game has improved graphics, new sounds, new bonus/jackpot and a totally new 'double-up' feature. Very addictive, in fact...
And here some shots of Sigma Poker 2000 (not working yet)...
After hooking/wiring all output ports, I hooked the lamps to all sets...
And here the promised list of changes...

--- 2007/11/07 ---
Well... Some time ago I made an attempt to rewrite the driver, but I got stuck with several things. Now, thanks to an anonymous collaborator that own the board, I received a lot of technical information that encouraged me to rewrite the whole thing again...
And a totally different set...
All sets are working properly with full sound.
I'll post a list of changes soon...
--- 2007/11/04 ---
A LEGEND is coming back to life...
More soon...
--- 2007/09/30 ---
I made some improvements to Snooker 10. The game use different hardware than funworld games and should be moved to its own driver. Still not playable and need a lot of work.
--- 2007/08/11 ---
I was trying to get back to the life a provided unknown set. The game was in fact a new version of the poker game called "El Grande", from Tuni Electro Service (1982). Inputs are multiplexed and I'm working on them right now, so hopefully we can get this one working properly for the next release.
Colors and GFX are properly decoded as you can see in the flyer.
--- 2007/07/14 ---
This is Mahjong Almond Pink from Dynax (1988). The game is running in a modified Royal Mahjong hardware and it has BIG explicit scenes (XXXXXXX rated!), so... the above snaps are the only ones that I can provide here ;).
What a shame!... The first time I got it booting, my wife and my little daughter were watching expecting mahjong tiles!... 8P
The game need more work and isn't working properly yet.
--- 2007/06/20 ---
Some program ROMs are bad. Also the color PROM is not dumped. This driver was made analyzing the program ROMs due to lack of information, pics, etc... The game isn't working.
- Confirmed the CPU as 6502.
- Confirmed the CRT controller as 6845.
- Corrected the total & visible area analyzing the 6845 registers.
- Crystal documented via #define.
- CPU clock derived from #defined crystal value.
- Decoded all gfx properly.
- Partially worked the GFX banks:
- 2 bank (1bpp) for text layers and minor graphics.
- 1 bank (3bpp) for cards, jokers, dices and big text graphics.
--- 2007/05/12 ---
(For all the gambling games lovers...)
When the intro is running...
Insert some coins.
Choose a balloon and raise it.
Then bet on the remaining balloons.
When finish, balloons will start to explode...
revealing numbers.
Finally the risen balloon will show a number.
If your balloons beat the risen one, you WON! :)
In fact is a very addictive game. Also got 7mezzo working :)
Colors are not totally accurate. Here some shots...
Here the list of changes...
- Figured out how the protection works.
- Removed the hacks/patchs that formerly allow boot the games.
- Figured out how the buffered inputs works.
- Demuxed all inputs for both games.
- Unified the memory maps from both games.
- Added NVRAM support to both games.
- Crystal documented via #define.
- CPU clock derived from #defined crystal value.
- Changed CPU clock to 833 kHz.
- Mapped DIP switches.
- Found the maximum bet DIP switch in magicfly.
- Removed flag GAME_NOT_WORKING for both games.
- Managed the planes to get the 3bpp GFX colors accurate.
- Renamed the ROMs acording to pcb pictures and ROM contents.
- Cleaned up and optimized the driver.
- Reworked/updated technical notes.
--- 2007/05/05 ---
Reworked and demuxed all the inputs in pmpoker driver removing all the hacks used. Also added lamp support and layouts to each game, among other things...
Some shots...
(they look bad due to resize)
Here the list of changes...
- Removed all inputs hacks.
- Connected both PIAs properly.
- Demuxed all inputs for each game.

- Replaced the remaining IPT_SERVICE with IPT_BUTTON for regular buttons.
- Updated technical notes.
- Cleaned up the driver. Now is better organized and documented.
--- 2007/04/25 ---
Mystery partially solved. I found a picture of the "CEI Video Poker" (system 904) that clearly show an error. The background is definitely blue. Note that you can see the words "Cal Omega 1981" burned at the bottom of the screen.
Side to side...
Detail with levels correction...
--- 2007/04/24 ---
In fact, the game is "Gaming Draw Poker" from Casino Electronics Inc.
The hardware seems to be an evolution of Jack Potten's poker. Former than 906iii system (CEI). They replaced the discrete sound system with a AY8910 to improve sounds. Different memory map, multiplexed inputs, blah blah blah...
Cards GFX have the following unused logo (Omega Electronics?)...
Here some shots...
The game is working properly with sound. Lamps are a big mess and I'm still trying to fix them. Palette pass through a transformation, so the background could be blue or black, either. Need to check it against the real thing (if one day appear!!). A big thanks to Tomasz Slanina that pointed me in the right direction to demux the inputs.
--- 2007/02/26 ---
Added 'Snooker 10' (1998, Sandiy). GFX have been decoded properly and the 'missing' color prom was found repeated 64 times inside a 27c256 ROM. The game isn't working due to protection, missing CPU/MCU (there is unknown code present) and lack of inputs.
Here the tiles from the title.
--- 2007/02/02 ---
I fixed the palette issue for these poker games. The 'missing' color code was found in another offset. Also added a new Golden Poker Double Up set that came from an original Bonanza's Mini Boy cabinet (thanks to Harun Basalamah that kindly dumped his board, with help of Helmut Broichhausen).
And added another revision of Pool 10 (thanks to f205v that kindly won the eBay bid for me and dumped the board)
If someone knows the real meaning of SG+ in the payout table (are in fact hundred units), please drop me a mail or post it here.
--- 2007/01/24 ---
Thanks to Guru, that kindly dumped the color PROM from his Potten's Poker board, I decoded and added proper colors to this game. Unfortunately there is just ONE color code that doesn't match the game colors. After tried different ways to decode it, I got the same results. This color code is composed only of blue, turning "invisible" the tile that has it assigned. The "missing" color code is critical to show the black cards corner. More to come...
Anyway, I have a workaround to fix it, but I want to wait for another PROM dump to compare. (hopely soon...)
--- 2006/12/24 ---
The missing piece has been found. Pool 10, that apparently was the father of some other italian gambling games. Still need a bit of work and code analysis. More to come...
Pool 10 (Italia) running...
Tortuga Family (Italia) running...
A big Thanks to MAME Italian Forum guys for all their efforts.
Merry Christmas and Happy New Year!!...
--- 2006/12/04 ---
I decrypted the italian Jolly Card encrypted GFX. Added some encrypted sets and made a lot of improvements...
Jolly Card (Italia, encrypted) running...
Big Deal colors (using jollycrd palette)...
Cuore 1 & Elephant Family real colors (decoded color prom)...
Elephant Family super game...
For all people that requested the changes, here is the change/log:
- Merged/splitted some machine drivers, memory maps and inputs.
- Unified get_bg_tile_info for all games.
- Mapped the input buttons in a better format (all games). Keys: 156-QW-ZXCVBNM.
- Added proper color PROM decode routines.
- Rewrote the technical notes.
- Splitted the driver to driver/vidhrdw.
- Corrected the screen size and visible area to magiccrd based on mc6845 registers.
- Added the remaining 2 GFX planes to magiccrd, but GFX are imperfect (bad decode or bad dump?). Color PROM need to be dumped.
- Royalcrd: Added all inputs and DIP switches.
Fixed memory map, gfx decode
Corrected screen size and visible area based on mc6845 registers.
Corrected CPU clock to 2mhz.
- New game added: Joker Poker. Not working due to use of custom encrypted CPU.
- New game added: Royal Card (Slovakia, encrypted). Not working due to use of a custom encrypted CPU.
- Fixed jolycdcr gfx to 4bpp.
- Other fixes to get jolycdcr running.
- Managed royalcdb to work, using the 2nd half of program ROM. (seems to be mapped that way)
- Managed jolycdit to work, but with imperfect graphics due to gfx encryption.
- Fixed CPU clock to 2MHz. in all remaining games.
- Fixed ay8910 frequency based on elephfam audio.
- Fixed ay8910 volume in all games to avoid clipping.
- Reworked jolycdcr inputs: The game was designed to work only with remote credits. After nvram init, set the payout dip to "manual".
- Reworked jolycdit inputs: After nvram init, set the payout dip to "manual" to allow work the remote mode.
- Set jolycdat as bigdeal clone. The game has the same layout/behaviour instead of the normal jolly card games, even when are sharing gfx roms.
- Added the bipolar PROM and GAL to jolycdit. Confirmed the GFX ROMs as good dumps.
- Added an alternate set of Elephant Family. This one lacks of test mode and doesn't allow to switch between min-max bets through stop1.
- Added color PROMs to cuoreuno and elephfam sets but still no routed. Also added PLDs (protected, bad dumps).
- Corrected jollycrd screen size and visible area based on mc6845 registers.
- Hooked, wired and decoded the color prom in jollycrd sets based on jolycdit redump. Now colors are perfect.
- Wired and decoded the color prom in cuoreuno and elephfam sets. Now colors are perfect.
- Wired and decoded the color prom in royalcrd. Now colors are perfect.
- Hooked, wired and decoded the color prom in bigdeal sets based on jolycdat (jollycrd palette).
Colors seems to be correct, but need to check against the real thing. Flagged as IMPERFECT_COLORS till a color PROM dump appear.
- Decrypted jolycdit gfx roms.
- Added set Jolly Card (Austria, encrypted).
- Decrypted jolycdae and managed the planes to show correct colors. The set is working properly.
All changes have been submitted today.
A big Thanks to MAME Italian Forum guys for all their efforts.

Since last update, I decided to rewrite the entire funworld driver because the thing was becoming a whole mess. Additionally, a lot of improvements were made. I'll post a partial list of changes later. For now, here are some shots...
Jolly Card...
Royal Card...
Both games are working properly with full sound and perfect colors.
Cuore 1 and Elephant Family have some odd things, but I'm planning to write a program that can run in the real hardware to output some answers... (thanks to f205v/kold/stekka that will send the boards).
--- 2006/10/28 ---
In fact, graphics are 4bpp. Cuore 1 palette was rewritten. I also recreated the Elephant Family colors based on a new set of screenshots, thanks to kold666 and stekka that kindly sent me all snaps requested. Colors are now very close to the original games. Here a side-by-side comparison.
Cuore 1 Joker...
Elephant Family...
"I still need some pictures of funworld games running (jolly card, bonus card, magic card, big deal, elephant family, royal card). If you can contribute providing some of them, please contact me here or through the mameworld.net forums".
--- 2006/10/22 ---
I recreated the Cuore 1 colors thanks to some screenshots that mame italia guys kindly sent some time ago. It seems to be a 5th color in the Joker, that means GFX are at least 3bpp instead of two. I need to verify more closely. For now is close to the original game. Here a side-by-side comparison.
And some others...
The test mode is now working properly...
I still need some pictures of funworld games running (jolly card, bonus card, magic card, big deal, elephant family, royal card). If you can contribute providing some of them, please contact me here or through the mameworld.net forums.
--- 2006/10/18 ---
I have Cuore 1 and Elephant Family working. All inputs were hooked and managed to pass the initial check. Now both sets are completely playable. The "Payout" button isn't working due to hopper and ticket stats are always 0 (empty). Colors are still wrong due to lack of color PROMs.
And some Elephant Family shots...
If you can contribute providing some pictures of these games running, please contact me here or through the mameworld.net forums.
--- 2006/10/07 ---
**** UPDATED ****
As you can see here, ROCK DUCK is not a legend anymore! ;-)
Colors are wrong due to missing color PROMs.
--- 2006/09/14 ---
After hard work, I hooked all the inputs. These are different for both games. PlayMan Poker have buttons with more than one function, while Golden Up Double Up have all functions separately.
Also fixed the 'Half Gambling' option. Now both sets are completely playable.
And some PlayMan Poker shots...
**** UPDATED ****
I accidentally inverted two colors when translating the palette to a better organized format. Here the changes for a side-to-side comparison.
--- 2006/09/11 ---
Some days ago, I submitted a preliminary driver for PlayMan Poker mostly based in the program roms analysis, since the dump was quite incomplete and lacks of technical references.
Haze added a set called Big Boy to this driver, which apparently has missing the 3rd plane of 2nd graphics bank.
Fortunatelly the 'undumped' roms appeared. Also a nice pic of the PCB... (thanks Haze!)
The Big Boy set, is in fact 'Golden Poker Double Up' from Bonanza Enterprises, and suspected to work on this hardware.
Since there's not a dumped color PROM for these games, I simulated the colors recreating the palette from the scratch following the color RAM codes.
Colors are now accurate and were based on some shots and flyers, thanks to Dan (TAFA) that kindly sent me hi-res scans of this game flyers.
Also found more than half of the inputs (no hold buttons yet), making this game partially playable.
--- 2006/08/06 ---
I found the bit that control the gfx banks. Based on this, I hooked the first graphics layer...
Not so bad?... Yes. Absolutely wrong.
After looked carefully to the rest of layers, I noticed that they are different bitplanes of 3bpp tiles instead of some kind of animation that I originally thought. Here some shots after correct graphics decode / layers...
Ok... Colors are still wrong, but now the graphics are properly banked / decoded.
New changes:
- Figured out how the gfx banks works.
- Fixed the gfx layers.
- Fixed the gfx decode.
- Removed flag GAME_IMPERFECT_GRAPHICS.
A less thing to do... :)
--- 2006/07/27 ---
Ok, fixed the NMI / vblank stuff. Now the magicfly attract/intro works... :)
Also confirmed the MC6845 mapped to $0800 - $0801. A piece of code initialize it writing to its registers. Analyzing the writes, I fixed the screen size and visible area. Now the aspect when render to 4:3 looks better.
- Input port at $2800: Code accept only bits 4, 6 & 7 as valid. If another bit is activated, will produce an I/O error.
- Lowered the CPU clock a bit. The text scroll in magicfly attract looks so fast with the former value.
Resuming, the new changes are:
- Figured out the MC6845 (mapped at $0800-$0801)
- Fixed the screen size based on MC6845 registers.
- Fixed the visible area based on MC6845 registers.
- Corrected the gfx rom region.
- Solved the NMI/vblank issue. Now attract works.
- Changed CPU clock to 625khz. (text scroll looks so fast with the former value)
- Added new findings to the technical notes.
- Added version/revision number to magicfly.
- Marked magicfly PAL as NO_DUMP (read protected).
- Added flags GAME_IMPERFECT_GRAPHICS and GAME_WRONG_COLORS.
A lot of things remaining. gfx banks, colors, inputs, sound, the mysterious $3000 writes. How close and how far...
Anyway... we're on. :)
--- 2006/07/25 ---
I was right when I thought that $0019 was a kind of counter. A NMI should be triggered to increment this register and allow continue the execution. For now, the game code is looping due to lack of this NMI. I'll check the NMI / vblank stuff later and will try to fix it.
Also tried something similar for 7mezzo. The program code at beginning is slightly different, and use different registers too.
I was not sure about the game itself since the real "Sette e Mezzo" is a kind of blackjack game where you need to reach 7 and half (instead of 21) to beat the dealer, and the italian manual for this PCB show DIP switch options to allow/disallow a Royal Flush (poker). Also the manual show another DIP switch to change between french and english (not italian) language and the text inside the program rom is clearly english.
Anyway... The game is IN FACT "Sette e Mezzo" (7 and half) or whatever the english name is.
Both games aren't working and need more efforts.
I will put all the technical stuff (disassembled code, analysis, reverse engineering, etc) online as soon as I find enough spare time.
--- 2006/07/21 ---
Program compare the content of $0067 with #$02, #$03, #$04, #$05 and #$E1. If #$E1 is found here, the machine hangs showing "I/O ERROR". I manually used #$02 and I'll put #$32 to $0019 to allow continue the execution. (see the following code)
CA71: A9 00 lda #$00 ; Write #$00 at $0019.
CA73: 8D 19 00 sta $0019
CA76: AD 19 00 lda $0019 ; Waiting for #$0a at $0019... (a port?)
CA79: C9 0A cmp #$0A
CA7B: D0 F9 bne $CA76
CA7D: 60 rts
CA7E: A9 00 lda #$00 ; Here the same, but waiting for #$04.
CA80: 8D 19 00 sta $0019
CA83: AD 19 00 lda $0019
CA86: C9 04 cmp #$04
CA88: D0 F9 bne $CA83
CA8A: 60 rts
CA8B: A9 00 lda #$00 ; Here the same, but waiting for #$32.
CA8D: 8D 19 00 sta $0019 ; With the hack used, the game stuck here
CA90: AD 19 00 lda $0019 ; waiting for #$32 to be written at $0019.
CA93: C9 32 cmp #$32
CA95: D0 F9 bne $CA90
CA97: 60 rts
I suspect that $0019 is not a port. It looks as a kind of counter.
More to come...
--- 2006/07/19 ---
I followed the code and changed some things to allow work some registers that previously were out of the execution due to the former hack.
The 'garbage' are characters properly placed, but from different graphics bank. I need to investigate how the graphics banks are working.
The code expect a value from the color RAM. If this one isn't correct, clean the screen and jump to a loop.
DA0C: A9 15 lda #$15 ; Fill the video RAM with spaces (#$20),
DA0E: 8D 5F 00 sta $005F ; and color RAM with #$15

DA2F: 60 rts
DA30: A9 00 lda #$00 ; Fill video & color RAM
DA32: 8D 1D 00 sta $001D ; with calculated values
DA35: A9 FF lda #$FF ; through $C111 subroutine

DA45: 20 83 CF jsr $CF83
DA48: 20 77 DB jsr $DB77
DA4B: 4C 30 DA jmp $DA30 ; Jump to a loop
SLOW... but improving. ;)
--- 2006/07/11 ---
I made some improvements to the Magic Fly driver.
Corrected the total number of chars to decode by rom. This allowed me to fix the graphics offset for the text layer and adjust the gfx rom region bounds properly. Just for testing purposes I tried a little hack to bypass some checks, and finally the game showed me something...
According to the following part of code:
CE44: A9 1F lda #$1F ; clean the screen
CE46: 8D 5F 00 sta $005F ; filling with #$1f
CE49: A9 20 lda #$20 ; the color ram,
CE4B: 8D 5E 00 sta $005E ; and filling with spaces
CE4E: 20 83 CF jsr $CF83 ; the video ram

After finish to work with Pairs Love DIP switches (0.106u10), I decided to take a look to an old preliminary driver I started some time ago. This one is for "Magic Fly" and "7 e Mezzo", running in the same 6502 based hardware. Both games aren't working yet, but at least they initialize video and color ram.
There are lot of things to do and fix, but today I submitted the driver "as is" to put the stuff "in a safe place".
--- 2006/05/27 ---
More fixes/improvements to jalmah.c DIP switches:
Kakumei:
- Added flip screen DIP switch.
Daireika, urashima & mjzoomin:
- Added flip screen DIP switch.
- Fixed test/service DIP switch.
- Fixed complete coinage. (This is related to coin1. Coin2 is always 1c/1c).
--- 2006/05/24 ---
- Fixed the demo sound DIP switch in horekid and horekidb.
- Fixed suchipi0106u1gra from mametesters.
This fix also improve the kakumei2 DIP switches.
I separated the DIP switches from kakumei, since they are different.
I'm making more improvements for this driver but need a LOT of tests, so I'll submit the rest when I finish them.

Aaron requested me to change the way to program the unused DIP switches, so I resubmited the correct stuff. Here the final changes:
hbarrel, hbarrelw :
- Removed the default dec0 coinage (wrong) and rewrote the complete coinage.
- Fixed "Difficulty" DIP switches.
baddudes, drgninja:
- Fixed "Difficulty" DIP switches.
- Changed "Unused" (DSW0, 0x80) to "Unknown" (according to some technical sources should be "Cabinet")
birdtry:
- New DIP switches from the scratch (separated from hbarrel)
- Added "Coinage" DIP switch.
- Added "Service" DIP switch.
- Added "Demo Sounds" DIP switch.
- Added "Flip Screen" DIP switch.
robocop and clones:
- Fixed "Difficulty" DIP switches.
hippodrm and clones:
- Fixed "Difficulty" DIP switches.
- Changed "Enemy Power on Continue" options from "ON / OFF" to "3 Dots / 2 Dots" (dots left in the enemy power on continue)
slyspy and clones:
- Fixed "Energy" DIP switches.
- Fixed "Difficulty" DIP switches.
midres and clones:
- Fixed "Difficulty" DIP switches.
- Put a note in both "Unknown" switches (DSW1 0x10 & 0x20) because some technical sources pointed them related to extra lives.
bouldash, bouldshj:
- Removed the default dec0 coinage (wrong), figured out the real one and rewrote the complete coinage from the scratch.
- Fixed "Difficulty" DIP switches.
- Removed "Unused" (DSW0 0x10) and the former "Demo Sounds" DIP switch (DSW0 0x20). Both are in fact part of the new coinage.
- Changed "Game" DIP switch title to "Game Change Mode" (according to technical sources).
- Added "Demo Sounds" DIP switch (DSW1 0x80).

NOTE ABOUT VIDEOPOKER SETS: Sorry, was my fault. But I recognized the error and corrected the driver
to use the original dumps. Changed the rom load for Elephant Family, and added a new set: Royal Card.
As I said, this one in a part of the code branch to 00 (brk). I need to analize better.
Also added some technical info for royalcrd and the fuse map for the PAL.
Was not my intention to hurt anybody.
I just want to contribute to preserve the games.

This one is working with the mcu. Not much time to test it. Copyright was ripped and replaced with the word "wait"
(same as the japanese bootleg 2). Also some dips were changed.

Rewritten the complete dipswitchs of Space Position (Japan), but validity checks complains about it...
Maybe an issue with the fake inputs. Need to check with Haze (after sleep =P).
