The Sega Saturn is a 32 bit 5th generation home video game console released by Sega in 1994. It has a total of 8 processors which makes it one of the most difficult consoles to emulate.
|Emulator||Rom Folder||Extension||BIOS||Controller Config|
|lr-yabause||saturn||.bin .cue .iso .mdf||saturn_bios.bin||/opt/retropie/configs/saturn/retroarch.cfg|
|lr-beetle-saturn||saturn||.bin .cue .iso .mdf||sega_101.bin, mpr-17933.bin||/opt/retropie/configs/saturn/retroarch.cfg|
Emulators: lr-yabause, lr-beetle-saturn
lr-yabause is experimental, and even with an overclocked RPi4B it is slow so it isn't recommended for Raspberry Pi users at this time.
lr-beetle-saturn is for x86 PCs only, and is recommended for those with such hardware.
Accepted File Extensions: .cue .bin .iso .mdf
Place your Sega Saturn ROMs in
Why don't my .bin or .iso files show up?
RetroPie is configured to only show .cue files in EmulationStation so that you do not have two copies showing up of all your games.
A .cue file is basically a plain text file that tells the emulator where in the .bin file the (data and/or audio) track(s) are. This is often important in the case where multiple audio files are in the single .bin file. These are often called "mixed mode" discs. Wikipedia .cue files
If you only have a .bin file and no .cue file, you can generate it:

The BIOS file needed for lr-yabause is saturn_bios.bin or for lr-beetle-saturn sega_101.bin (Required for JP games) and mpr-17933.bin (Required for US/EU games)
Place your BIOS in
lr-yabause and lr-beetle-saturn utilise Retroarch configurations
Add custom retroarch controls to the retroarch.cfg file in
The standalone version runs faster but requires X, QT, etc. Even then, it manages 10FPS so probably not worth adding to the scripts. If you're curious, here's the basic instructions to get it installed:
sudo apt update sudo apt install xinit qt4-dev-tools build-essential libgl1-mesa-dev
mkdir tempdev cd tempdev
git clone https://github.com/Yabause/yabause.git cd yabause/yabause/src cmake -DYAB_WANT_OPENGL=NO $SOURCES make
go into a terminal on your pi itself
navigate to /your_directory/yabause/yabausesrc/qt
sudo xinit ./yabause
