This is an NES emulator written in Go.
The link below contains hundreds of screenshots that were generated automatically by loading a ROM, emulating for a few seconds and then saving the screen.

The following mappers have been implemented:
- NROM (0)
- MMC1 (1)
- UNROM (2)
- MMC3 (4)
These mappers cover about 75% of all NES games. I hope to implement more mappers soon. To see what games should work, consult this list:
- the APU DMC channel is not yet implemented
- there are some minor issues with PPU timing, but most games work OK anyway
- some games just show a black screen, not sure why yet
