Sega Saturn emulator, a fork of uoYabause. Improved performance and OpenGL rendering compared to the original Yabause.

1. Installation

  1. Download the latest release from the project's official website.
  2. Extract the archive into a dedicated folder.
  3. Launch it once: it will create its configuration and subfolders.

2. System files

This emulator relies on files taken from the original hardware. Extract them from hardware you own.

Files expected according to our listing:

  • Saturn BIOS (.bin)

Indicated location: /bios/saturn/

Depends on region

3. Supported formats

.cue .chd .iso

.chd is lossless compression: a single, much lighter file per game.

4. Good to know

  • Set up your controller on first launch: it saves the most time.
  • Save states let you pick up right where you left off, in addition to in-game saves.
  • On these systems, raising the render resolution noticeably improves the image; dial it back a notch if it stutters.

5. Not working?

  • Refuses to start or black screen → a system file is missing, misnamed, or not in the expected location.
  • File rejected → its checksum doesn't match the expected one; the dump is probably incomplete or from a different model.
  • Game doesn't show up → check that its extension is among the formats listed above.
  • Abnormal display → try a different rendering backend in the options, and check your graphics drivers.
