Notes:
- All chips are 20-pin 0.3" PDIP
- Register $8000 is at $8000-$BFFF
- Register $C000 is at $C000-$FFFF
- ?? is unknown input, tied to GND in all cartridges
- BF9093 is used in 64 kB /128 kB /256 kB NES & 64 kB Famicom singles (iNES Mapper 071 submapper 0)
- BF9096 is used in NES/Famicom Quattro multicarts (iNES Mapper 232)
- BF9097 is used in Firehawk (iNES Mapper 071) submapper 1 and in 64 kB Famicom singles (pins 17, 16 are not wired here)
- CIC stun latches inverse of CPU A0 when writing at $E000-$FFFF
- Pinout from Kevtris is not accurate
