Emulator: Supermodel
RetroPie includes a fork of the Supermodel emulator that adds Sinden lightgun support with 2 player support in Linux/MacOS, with an additional ARM friendly branch, mainainted by DirtBagXon. For ARM devices, it needs at least a Pi4 (or equivalent SBC) to play the games at an acceptable speed. Some games will not be playable without overclocking (CPU/GPU).
When starting a Sega Model 3 game from the arcade folder, use the runcommand launch menu to choose the Supermodel3 emulator to play the game. The menu includes the following emulators:
- supermodel3: default entry, runs the emulator with the default video resolution of the original arcade board. Recommended for low-powered devices, to be used in conjunction with a lower resolution video mode in order to fill most of the screen.
- supermodel3-scaled: additional entry that scales the viewport to the display's video resolution. It will run the emulator fullscreen, but it needs additional processing power to scale the image. This entry should be used on a powerful system (i.e. PC).
- supermodel3-legacy (x86 only): additional entry for PC systems that are too weak to run the emulator with the new 3D renderer, it uses the legacy3d renderer for the video output.
To configure default options for all games or per-game options, the Supermodel.ini configuration file can be used. The parameters available are usually accompanied by the corresponding documetation in the file, the emulator's documentation can be consulted online here.
ROMS
Accepted File Extensions: .zip
Place your arcade ROMS in:
/home/pi/RetroPie/roms/arcade
Note: the emulator accepts additional per-game parameters when run by specifying the desired parameters in a separate <ROM>.commands text file, which should be places next to the ROM.zip ROM file. For instance, to activate force feedback for Daytona2, a daytona2.commands file should be created next to the daytona2.zip file, containing:
-force-feedback
Any parameter/option accepted by the emulator should be placed in the .commands file, separated by a newline or spaces.
Controls
The controls are configured in the following configuration file:
/opt/retropie/configs/arcade/supermodel3/Config/Supermodel.ini
The emulator will auto-detect the gamepads connected and assign the default values configured in the configuration file. Common controls mapping is given below and each game can have it's own set of configuration.

Lightgun support
To activate the outline border needed by the Sinden Lightgun devices, add a .commands file for the game that should contain the -borders=1 or -borders=2 parameters. Other lightguns that emulate a mouse will not need the additional file and should work as-is.
