PlayStation Emulation

Libretro offers 3 different cores to emulate Playstation games.

  • PCSX Rearmed: This core offers basic emulation with no advanced features. It can fallback to an emulated BIOS if none is found but it is still recommended to provide a BIOS for compatibility reasons.
  • Beetle PSX: This core offers more precise emulation compared to PCSX but will require a valid BIOS file.
  • Beetle PSX HW: This is like the Beetle PSX core but with advanced rendering options. This core will give you the best visual results.

Setting up BIOS files

Playstation BIOS files have to be placed in RetroArch's system directory (by default: ~/.config/retroarch/system). Make sure the files are correctly named and have the correct MD5 sum. The list below gives you the supported BIOS files and their checksums.
