M14 Hardware (c) 1979 Irem
driver by Angelo Salese
TODO:
- Actual discrete sound emulation;
- 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/Os are grossly mapped;
- ball and paddle drawing are a guesswork;
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;
- After getting a completed hand, press start 1 + ron + discard at the same time to go back
into attract mode (!);
