Assorted things...

Added a new Jolly Card dump from Team Europe and Rock Shebbich. The game is an italian bootleg and the strange thing is that doesn't need NVRAM initialization to start to work. Here is the PCB:

Royal Jackpot...

A new board acquired by Team Europe.

Royal Jackpot PCB

This is a modified Royal Card that allow a third deal (still can't find how :-P ), but looks interesting. The game has encrypted graphics like the blue TAB PCB. The encryption scheme is similar:

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:


Being X & Y the encrypted nibbles...

decrypted_byte = ((X ^ (X >> 1)) << 1 ) + (((Y ^ (Y >> 1)) >> 3) & 0x0f)



Here are some snaps...

Royal Jackpot Royal Jackpot Royal Jackpot Royal Jackpot

Now decrypted... :)

Will see if we can get the way to get the third deal working...

More rare platforms...

I'm working on a new dump from caius, The game is a not identified poker type gambling game running in a Z80 + AY-3-8910 hardware. The PCB is not working but caius told us that will try to resurrect it (we need it to check colors, tile banking, etc...)

unknown italian poker game PCB

Some snaps of the game working:

With the whole input system working...

With a hack from AJR to get the correct graphics (we can't find a selector for the tile bankswitching) :(

We need to find the tile bankswitching selector, otherwise the bookkeeping will looks broken. Anyway... The game is playable now.

Another rare platform...

I'm working on a new driver for this rare Z80 + AY-8910 based PCB, dumped by Arzeno Fabrice. The game is unknown and need to be identified. The PCB is not working, but following the marks, the only thing we have is that seems it was manufactured in France.

unknown French PCB

Data and addressing lines are encrypted/scrambled. However, I decoded the graphics. Here you can see the tiles manually arranged.

unknown French game (arranged tiles)

If someone can help to identify this game, I'll appreciate some feedback in the MameWorld forums, or just drop me a PM or mail through "contact" here.



********** EDIT **********

Well... Haze pointed me that this hardware belongs to '4 En Raya' driver... Now it's working in the correct driver. The game is in fact a 'Stealth' game. A sort of a gambling game hidden into a 'Space Invader' front game, to avoid the anti-gambling laws...

Here some snaps...

********** EDIT #2 **********

Now a second set appeared!... This one has worse addressing things, but now it's working too!. This set has graphics for 'Space Invaders' and also for the 'Pac-Man' gambling game that runs in similar hardware. I think it's just a leftover.

Mega Double Poker & Golden Poker Double-Up...

Some years ago, I wrote a driver for Blitz's Mega Double Poker. The hardware was close to Bonanza's Golden Poker Double-Up, but using a protected 68705 MCU. Now, thanks to Caps0ff hard work decapping the device, we have the extracted program.

AJR was kind enough to hook the MCU, and finally the driver was merged with the Golden Poker Double-Up one. The game is finally working!!... Here some snaps.

Also Arcade Vintage dumped a clone of Golden Poker Double-Up from a bootleg board, that looks similar to Potten's poker, but the hardware has the same full addressing mode seen in the Bonanza's game...

Gran Premio F1 (Spanish)...

Thanks to Arcade Hacker and Rockman, we have Gran Premio F1 (spanish bootleg of Pole Position II) dumped. :-)

This bootleg has a TMS5220 for spanish voices instead of the Namco 52xx. For now the spanish voices aren't working due to the lack of proper implementation.

Here some snaps.
