This repo contains patches to add Famicom Expansion port controllers compatibility.
https://github.com/darthcloud/famicom-exp-patches
These patches are for headered iNES ROM.
Support for internal controllers is maintained in most case.
- Battletoads
- Snake Rattle n Roll
- Terminator 2
The original poll function is quite optimized already and the bank in which the poll function is located do not have obvious empty space to allow relocation/split of the poll function.
Some version of those games do support controller on the Famicom expansion port:
- Link no Bouken - The Legend of Zelda 2 (Japan) (FDS)
- Paperboy (Japan) (FC)
- Pinball (Japan) (FDS)
- Pinball (Europe) (NES)
- RoboCop 2 (Japan) (FC)
- Star Force (Japan) (FC)
- Terminator 2 (Japan) (FC)
- Yume Koujou - Doki Doki Panic (Japan) (FDS)
