/********************************************************************************************** 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; ============================================================================================== x (Mystery Rom) (c)1978-1981?
