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
Yabause stands for: Yet Another Buggy And Uncomplete Sega Emulator. It stands by its name. Currently you need to install it from the setup script under experimental builds. Any Raspberry Pi model will achieve only 1-2 frames-per-second, rendering it unplayable on those systems. Saturn is really only recommended for use on a PC and even then emulation is less than perfect.
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
For more information on custom RetroArch controls see: RetroArch Configuration
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-get update sudo apt-get install xinit qt4-dev-tools build-essential libgl1-mesa-dev
make some directory, and go in it
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
