Nintendo - SNES / Famicom (Beetle bsnes)¶

Background¶

Standalone port of Mednafen bSNES to libretro, itself a old fork of bsnes 0.59.

This core exists as a side effect of porting/forking mednafen for its other cores in the past. There's no reason to use this core now that there's other more compatible and faster SNES cores.
