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 serialized by the chip included on the board.
Since NEO-ZMC2 isn't present, NEO-ZMC is used to bankswitch the M1 ROM.
The cartridge connector has 2*2*60 (240) pins. See MVS cartridge pinout.
Trivia
- Early cartridges like Puzzled and NAM-1975 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, Fatal Fury 2 and Metal Slug X - Super Vehicle-001 have a challenge/response type protection and banking chip called SNK-9201.
- Some carts like King of Fighters '98 - Dream Match Never Ends 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 ?
