Looking at an unknown Irem M14 game that was recently dumped…after some hooking up (and actually realizing that there  wasn’t a MAME driver for Irem M14 HW running on an I8085A), I’ve managed to let it work. The game is actually named PT Reach Mahjong , and yes, it’s a 1 player mahjong game without an opponent that can be treated as a sort of practice mode. 😉
