PRO-CT0 are early DIP64S GAL (Gate Array Logic) 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]].
