YabaSanshiro is a Sega Saturn core for RetroArch and a fork of Yabause, according to the official libretro documentation. This guide restates what that documentation specifies about the core, so you know its hardware requirements, accepted file types and BIOS expectations before installing it.

Graphics requirements

YabaSanshiro requires OpenGL 3.3 or OpenGL ES 3.0, per the official documentation. Check that your graphics driver and RetroArch video context can provide one of those before expecting the core to run.

BIOS file

The documentation lists saturn_bios.bin as an optional BIOS file for the core. The stated MD5 checksum, af5828fdff51384f99b3c4926be27762, is described as a hint rather than a requirement, and any valid Saturn BIOS should work.

Supported disc image extensions

The documented content extensions for the core are .cue, .iso, .ccd, .mds, .chd and .zip. The documentation maps the core to the Sega - Saturn database.

Authors and license

The documentation credits Guillaume Duhammel, Theo Berkau, Anders Montonen and devmiyax, and states the project is licensed under GPLv2.
