Merit Poker (c) 1983 Merit Industries, Inc.


Game's ROM.

MAME Info:

0.129 [David Haywood, Angelo Salese]


- 0.133u1: Angelo Salese improved colors in Multi-Poker. Changed palettesize to 512 colors.

- 0.133: Roberto Fresca fixed Multi-Poker - Game now playable. Merit Multi-Poker improvements [Roberto Fresca]: 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. The 4 games are fully playable. Sound seems to be discrete, so the circuitery need to be traced. Colors are still wrong. Changed description of 'Merit Poker' to 'Multi-Poker'. Changed Z80 CPU1 clock speed to 3MHz. Changed year to 1981. Added dipswitches 'Coin A', 'Game Select', 'Maximun Bet' and 'Main Percentage'.

- 20th July 2009: Roberto Fresca - 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.

- 0.129: David Haywood and Angelo Salese added Merit Poker (Merit 1983).

- 22nd October 2005: ClawGrip - Another game dumped: Multi Poker (1981), from Merit Industries. The small sub-board is a Video I-O.
