sSNES
A Super Nintendo Entertainment System (SNES) emulator for s&box, written entirely in C#.
This is a proof of concept! The emulator is functional enough to run a selection of games, but it is not a complete or accurate SNES implementation. Audio is not working in most games. Not all ROMs are expected to work, and compatibility varies significantly by game and mapper type.
Supported Formats
- `.sfc` / `.SFC` — Super Famicom / SNES ROM
- `.smc` / `.SMC` — Super Magicom format
LoROM, HiROM, and ExHiROM mappers are supported. SA-1 and SuperFX coprocessors are partially emulated.
Adding ROMs
Place your ROM files in the `roms` folder inside your local addon data directory:
sbox/data/ssnes/roms/
Subdirectories are supported, so you can organise your library into folders. The in-game browser will automatically pick them up.
Compatibility
Save Data: From the tests I've done, ROM save data works.
Save Data: From the tests I've done, ROM save data works.
LoROM games: Most standard LoROM games will boot and reach gameplay, but with significant issues:
- Rendering bugs (e.g., Link to the Past has incorrect tiles after leaving the house)
- Anti-piracy screens (e.g., Earthbound, Tetris 2)
- Some titles fail to boot entirely (e.g., Kirby)
HiROM games: Limited testing.
Enhancement chips:
- SuperFX: Not working (e.g., Starfox, Yoshi's Island)
- SA-1: Status unknown
- DSP-1: Status unknown
Audio: Functional in many games, but may have accuracy issues.
