The NES MMC5 chip was rather ace as it gave you another couple of audio channels to play with - it’s rather nice to make tunes on (tho not a patch on VRC-6…) > in short it gave you 2x extra squarewave channels to play with…
Using a bit of music software like Famitracker one can make a little MMC5 compatible ditty and combined with the following instructions hopefully it’ll finally encourage peeps to get the things playing on real non-emulated hardware…

Please note: In order to hear extra sound channels from the MMC5 chip - using a real Famicom is recommended unless you want to modify your carts / converter + console further…
1) Pull up pins: 01,02, 22, 24, 30, 31 on both eproms
2) On the PRG chip:
Wire Eprom:
- leg 01 -> Leave floating
- leg 02 -> Board hole 24 (MMC5: A16)
- leg 22 -> Board hole 31 (MMC5: /CE)
- leg 24 -> tie to GND -> PIN 16 of the EPROM is a good place.
- leg 30 -> Board hole 01 (MMC5: A17)
- leg 31 -> board hole 02 (MMC5: A18)
3) On the CHR chip:
Wire Eprom:
- leg 01 -> Leave floating
- leg 02 -> Board hole 24 (MMC5: A16)
- leg 22 -> Board hole 31 (MMC5: /CE)
- leg 24 -> Board hold 22 (MMC5: /A13)
- leg 30 -> Board hole 01 (MMC5: A17)
- leg 31 -> board hole 02 (MMC5: A18)
As an added bonus by providing the info for free unlike some other unmentionables; it’ll really annoy the $$$ hungry repro makers :P
