Sony PlayStation (PS1 / PSX) [RetroPie series]

Evan-Amos via Wikipedia

Here are my Sony PlayStation specific notes of my RetroPie system. The PS1 emulator runs on RetroArch, so you may want to check out common RetroArch stuff I posted separately.

• RetroPie PS1 wiki
• libretro-pcsx
  • TODO: Update to more optimized lr-pcsx-rearmed

Performance can be an issue with some Playstation games. Overclocking and using libretro-pcsx-rearmed should get pretty good result (but not 100% accurate) emulation on Raspberry Pi 2.

Games

• Game manuals
  • Games Database
  • ReplacementDocs
• RetroPie
  • Extract .zip → .bin to ~/RetroPie/roms/psx/
  • If game comes on multiple CD, move additional images to ~/RetroPie/roms/psx/.MoreDisks (NOTE! Not tested)

BIOS

BIOS needs to be copied from an original PS1 or downloaded.

Controllers

Using PlayStation controller via Bliss-Box 4-Play

I am currently using black DualShock controllers (“PS2 controllers”) as there seems to be a problem with analog shoulder buttons (not sure if I there still are issues with games using the lower shoulder buttons). The configuration is at /opt/retropie/configs/psx/retroarch.cfg:

Using USB-connected PS3 controllers

PS3 controller is a natural match for PS1 games.
