MAME Info:

0.125u1 [Roberto Fresca]


- The first time you run the game, it will say 'DATA ERROR'. Press F3 to initialize the NVRAM.


- 0.128: Roberto Fresca improved Poker 4-1 button-lamps layouts to look more realistic.

- 0.127u1: Game-A-Tron gambling hardware updates [Roberto Fresca]: Added sound support to Poker 4-1 and Pull Tabs. Figured out the output ports. Documented each bit accessed. Added button lamps support. Created layouts for both games. Switched the 8255 port C to be used as output port. Adjusted the coin pulse timing. Updated technical notes. Splitted the driver to driver + video. Final clean-up. Added SN76496 (2MHz) sound.

- 0.125u4: Improvements to Game-A-Tron [Roberto Fresca]: Changed description to 'Poker 4-1' as shown in the ROMs stickers. Renamed the ROMs according to their own stickers. Moved the driver into gametron.a group. Added the missing input port C to 8255 PPI I/O chip. Poker 4-1 don't make use of it, but is present in the Test/Setting Mode. Updated technical notes. Renamed (gatcards) to (poker41).

- 0.125u1: Roberto Fresca added Card Games? (Game-A-Tron 1983).

- 12th May 2008: Roberto Fresca - Two old different Game-A-Tron 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 (http://mamedev.org/contact.html), or post something in the MAMEWorld Forums.
