Yabause running the Japanese Saturn BIOS.

Yabause is an open source emulator for the Sega Saturn. It runs on mainly on Windows, Linux, OpenBSD and Mac OS X systems using OpenGL and SDL, although an unofficial FreeBSD port is available and a primitive Dreamcast port exists.


Development of Yabause began primarily for Linux, with the first release on September 12, 2003. Windows and MacOS support came at version 0.0.6 on July 5, 2004.
