Emulators: lr-genesis-plus-gx, lr-picodrive

lr-genesis-plus-gx is recommended for the Pi 2/3 as it has better accuracy.

ROMS

Accepted File Extensions: .bin .chd .cue .iso, .m3u for multi-disc games.
Note: .bin files won't be displayed within Emulation Station, they will be referenced via the .cue.

Place your Sega CD ROMS (.chd .iso OR .bin AND .cue) in

/home/pi/RetroPie/roms/segacd

If you don't have the corresponding .cue file in the same folder as your .bin file, your game may not have sound.

Multi-Disc games

For multi-disc games using .cue or .chd format, you can create a .m3u playlist to be able to easily change discs from the RetroArch's Disk Control menu.

To change the disc through RetroArch, from the "Quick Menu", enter "Disk Control", use the "Disk Cycle Tray Status" to open the virtual disk tray, change the disk number to the correct one, then use the "Disk Cycle Tray Status" to close the virtual disk tray.

Example playlist for Fahrenheit:

Folder Structure:

  • Fahrenheit (Disc 1).cue
  • Fahrenheit (Disc 1).bin
  • Fahrenheit (Disc 2).cue
  • Fahrenheit (Disc 2 - track1).bin
  • Fahrenheit (Disc 2 - track2).bin

Contents of the .m3u playlist

Fahrenheit (Disc 1).cue
Fahrenheit (Disc 2).cue
