American Video Entertainment made a bunch of games for the NES console, though alot of them were just US re-released of 3rd party titles made by obscure Taiwanese companies. They used discrete logic mappers, and had a couple "Nina" lockout defeater chips which appear to be nothing more than programmed microcontrollers.
The Boards and mappers:
NINA-03 - Max. 32K PRG, 32K CHR, Discrete logic mapper.
MB-91 A - Max. 32K PRG, 32K CHR, Early rev of NINA-03.
NINA-06 - Max. 64K PRG, 64K CHR, Discrete logic mapper, most common.
MB-91 H - Max. 64K PRG, 64K CHR, Early rev of NINA-06.
D-1012 - Max. 1Mbyte PRG, 1Mbyte CHR, Maxi-15.
