MAME Info:
0.37b8 [Takahiro Nogi]
< Japan >
Bugs:
- Crashies because of nested NMIs, to fix that I bumped the clock from 5 MHz to 10 MHz. Source (ID 02394)
WIP:
- 0.86u2: Changed Z80 CPU1 clock speed to 5MHz.
- 0.65: Changed Z80 CPU1 clock speed to 10MHz. Added user1 rom ($0 - protection data), this ROM was not dumped, but the program expects the same checksum as the gfx1 rom 1i.bin from housemnq, so it's a safe assumption that it's the same. Added 10x 'Unknown' dipswitches.
- 0.64: Changed description to 'Mahjong Focus (Japan 890313)' and clones to 'Mahjong Focus [BET] (Japan 890510)' and 'Nozokimeguri Mahjong Peep Show (Japan 890404)'.
- 0.37b8: Takahiro Nogi added Mahjong Focus (Japan) (Nichibutsu 1989) and clones [BET] (Japan) and Nozokimeguri Mahjong Peep Show (Japan).
