Emulators: lr-nestopia, lr-fceumm, lr-mesen, lr-quicknes, lr-fbneo

ROMS

Accepted File Extensions: .7z .fds .nes .zip - make sure your roms have headers. Roms without headers will not work. If you want to use PAL roms, make sure they contain (E) or (Europe) in the filename, or else they may be run at the wrong speed.

Place your NES Roms in

/home/pi/RetroPie/roms/nes

NOTE: lr-fbneo expects the game roms to be in .zip/.7z archives named in a similar fashion to arcade romsets, so the filenames of the roms is important. Use a romset validation/building program like Clrmamepro or RomCenter to have the correct filenames, using the FBNeo NES DAT file file and a No-Intro NES ROM collection.

BIOS

FDS games require the disksys.rom bios file. Place the BIOS in:

• /home/pi/RetroPie/BIOS for lr-fceumm and lr-nestopia
• /home/pi/RetroPie/BIOS/fbneo for lr-fbneo, zipped in a file named fdsbios.zip

Controls

All three emulators utilise Retroarch configurations. Add custom RetroArch controls to the retroarch.cfg file in

/opt/retropie/configs/nes/retroarch.cfg

For more information on custom RetroArch controls see: RetroArch Configuration

Game Genie support

Game Genie was a popular video game cheat cartridge that temporarily modify game data, allowing the player to cheat, manipulate various aspects of games, and sometimes access unused assets and functions. It was available for NES, SNES, Game Boy, Sega Genesis and Game Gear.

Support for emulating a Game Genie cartridge is available in lr-fceumm:

• switch on the Game Genie Add-On (Restart) core option
• copy the Game Genie ROM file named gamegenie.nes in the BIOS folder (/home/pi/RetroPie/BIOS). gamegenie.nes checksums - CRC: A5D0515C, MD5: E354FB5B20E1B9FE4E5CA330F9B3391A

After enabling Game Genie Add-On core option, launching a game will cause the Game Genie boot screen to appear. Codes can be entered with the gamepad (as on real hardware): D-Pad to move, A to select, B to delete. Pressing the Start or Select buttons will load the game with the cheat code applied.
