Well I guess for those of you who love Mahjong games in MAME, Luca Elia has added a  gambling by Taiwanese Subsino, that uses Mahjong tiles instead of cards. Its name roughly translates to Sakura Love (actual title?):

Luca has  written three drivers for games by Subsino. This game, as figured out by Angelo, runs on the tilemap based hardware emulated in bishjan.c, but with an AMD AM188EM CPU (basically an 80188 + peripherals).

This game uncovered some previously unemulated features of the video chip, such as row and column scroll. And, unlike other Subsino games, this one has emulated sound since it uses an M6295 and an YM3812.
