PRO-CT0
PRO-CT0 are early SDIP64 gate array chips used as:
- Sprite graphics multiplexers on AES carts and MVS boards, sometimes named ALPHA-8921, later replaced by NEO-ZMC2 and then NEO-CMC.
- Security devices in AES and MVS cartridges like Super Sidekicks and Fatal Fury 2, later renamed SNK-9201.
