RMG is a fairly straight-forward emulator to set up. If you are strictly playing Nintendo 64 ROMs, place your ROMs in Emulation/roms/n64. No additional setup is required. Read the Configuration section to learn more about RMG and its folder locations.

To launch your ROMs in game mode, use Steam ROM Manager and use one of the following parsers to play your N64 ROMs:
