+/***************************************************************************
+ Munch Mobile
+ (C) 1983 SNK
+
+ 2 Z80s
+ 2 AY-8910s
+ 15 MHz crystal
+
+ Known Issues:
+ - it's unclear if mirroring the videoram chunks is correct behavior
+ - several unmapped registers
+
+Stephh's notes (based on the game Z80 code and some tests) :
+
+ - The "Continue after Game Over" Dip Switch (DSW1:1) allows the player
+ to continue from where he lost his last life when he starts a new game.
+ IMO, this is a debug feature (as often with SNK games) as there is
+ NO continue routine nor text for it in the ROMS.
+ See code at 0x013a ('joyfulr') or 0x013e ('mnchmobl') for more infos.
+ - There is extra code at 0x1de2 in 'mnchmobl' but it doesn't seem to be used.
+
+- DIPs are now verified from Munch Mobile manual and playtesting.
