M14 Hardware (c) 1979 Irem
driver by Angelo Salese
TODO:
- Sound (very likely to be discrete);
- Colors might be not 100% accurate (needs screenshots from the real thing);
- What are the high 4 bits in the colorram for? They are used on the mahjong tiles only,
left-over or something more important?
- I'm not sure about the hopper hook-up, it could also be that the player should press
start + button 1 + ron buttons (= 0x43) instead of being "automatic";
- Inputs are grossly mapped;
Notes:
- Unlike most Arcade games, if you call a ron but you don't have a legit hand you'll automatically
lose the match. This is commonly named chombo in rii'chi mahjong rules;
- If you make the timer to run out, you'll lose the turn but you don't get any visible message
(presumably signaled by a sound effect);
- As you could expect, the cpu hands are actually pre-determined, so you actually play alone
against a variable number of available tiles;
