/****************************************************************************************** Sengoku Mahjong (c) 1991 Sigma driver by Angelo Salese & Pierpaolo Prazzoli Uses the same Seibu custom chips of the D-Con HW. TODO: - Find what the remaining video C.R.T. registers does; - Fix sprites bugs at a start of a play; - Check NVRAM boudaries; - How the "SW Service Mode" (press F2 during gameplay) really works (inputs etc)? Nothing mapped works with it... Notes: - Some strings written in the sound rom: "SENGOKU-MAHJONG Z80 PROGRAM ROM VERSION 1.00 WRITTEN BY K.SAEKI" at location 0x00c0-0x00ff. "Copyright 1990/1991 Sigma" at location 0x770-0x789. - To bypass the startup message, toggle "Reset" dip-switch or reset with F3. - If the Work RAM is not hooked-up (areas $67xx),a sound sample is played.I can't understand what it says though, appears to japanese words for "RAM failed". - Playing with the debugger I've found this -> http://img444.imageshack.us/img444/2980/0000ti3.png (notice the "credit" at the bottom). Maybe a non-BET version exists? Or there's a jumper setting?
