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.

Known PRO-CT0 markings to be of the graphics chip type: 9020KX032, ...

Marking of SNK-9201's: 9246EX020, 9247EX010, 9247EX007, 2947EX029

Marking of PRO-CT0's on AES PROG PCBs: 9042KX023
