MVS cartridge

Unlike AES cartridges, the sprite graphics aren't pre-serialized by a NEO-ZMC2 or PRO-CT0 chip. The complete C ROM data bus is exposed to the cartridge edge, it's then decoded by the chip included on the board.

Since NEO-ZMC2 isn't present, NEO-ZMC is used to multiplex the ADPCM-A and ADPCM-B data accesses to the V ROMs.

The cartridge connector has 2*2*60 (240) pins. See pinouts.

Trivia

 * Early cartridges like Puzzled and NAM1975 used lots of discrete logic chips for banking. These chips were quickly merged in ASICs like NEO-273, NEO-ZMC2, PCM, NEO-CMC...
 * [Super Sidekicks] and [Fatal Fury 2] have a challenge/response type protection and banking chip called SNK-9201.
 * Some carts like [KOF 98] had Altera MAX CPLDs as protection devices.
 * [Thrash Rally], [Riding Hero], and [League Bowling] had HD6301 microcontrollers and SN75176 differential bus drivers to communicate point-to-point through 3.5mm jack cables for their multiplayer mode. The AES versions only had one plug ?
