Discrete logic mappers

Only the ones not made by Nintendo.

This table describes the mappers as they existed, as opposed to any obvious oversize extensions.

See also Comparison of Nintendo mappers and User:Lidnariq/Discrete Logic Table.

You probably don't actually want to use these.

† Mappers 89, 93, and 184 exist as a single IC, however their functions are trivially described using a small number of 7400-series ICs, and likely contain multiple silicon dice that were wire bonded together in the same package.

‡ Mapper 93 is technically the same 89 other than mirroring, but it only commercially existed using 8kB of CHR-RAM

* the Vs System distributed its original games as five or six 8 KiB ROMs, and decoding on its mainboard allowed banking of CHR like CNROM. It is a little disingenuous to claim that 0 ICs were necessary for banking since the same functionality is not possible on a Famicom, however, banking was incrementally free.

§ Doesn't have CHRROM, hence "-1" ICs
