* 8-in-1 Rockin' Kats, Snake, (PCB marked as "8 in 1"), similar to 12IN1,
* but with MMC3 on board, all games are hacked the same, Snake is buggy too!
*
* no reset-citcuit, so selected game can be reset, but to change it you must use power

/*
MMC3-based multicart mapper with CHR RAM, CHR ROM and PRG RAM
$6000-7FFF: A~[011xxxxx xxMRSBBB] Multicart reg
This register can only be written to if PRG-RAM is enabled and writable (see $A001)
and BBB = 000 (power on state)
BBB = CHR+PRG block select bits (A19, A18, A17 for both PRG and CHR)
S = PRG block size & mirroring mode (0=128k with normal MMC3, 1=256k with TxSROM-like single-screen mirroring)
R = CHR mode (0=CHR ROM 1=CHR RAM)
M = CHR block size (0=256k 1=128k)
ignored when S is 0 for some reason
Example Game:
--------------------------
7 in 1 multicart (Amarello, TMNT2, Contra, Ninja Cat, Ninja Crusaders, Rainbow Islands 2)
