Setting Up BIOS and ROM Files

Proper BIOS and ROM file management is crucial for successful PS1 emulation. Incorrect file placement is the most common issue users encounter, so follow these instructions carefully.

Place BIOS files in Emulation/bios folder and ROMs in Emulation/roms/psx folder. The file structure must be exact – emulators won’t find files in subfolders or incorrect locations.

BIOS File Requirements

Your PS1 emulator needs BIOS files to replicate the original PlayStation hardware. Without proper BIOS files, games won’t run correctly.

Required BIOS Files:

  • scph5500.bin (Japan region)
  • scph5501.bin (North America region)
  • scph5502.bin (Europe region)

File Placement Instructions

  1. Connect to Network: Ensure your Steam Deck is connected to WiFi
  2. Access File Manager: In Desktop Mode, open the Dolphin file manager
  3. Navigate to SD Card: Go to /run/media/mmcblk0p1/ (or your SD card name)
  4. Create Emulation Folder: Create folder structure: Emulation/bios
  5. Place BIOS Files: Copy your BIOS files directly into the bios folder
  6. Create ROMs Folder: Create folder structure: Emulation/roms/psx
  7. Place Game ROMs: Copy your PS1 game files (.bin/.cue, .img, .iso, .pbp) into the psx folder

ROM vs ISO: ROM files contain game data, while ISO files are disc images. PS1 games typically come in .bin/.cue pairs (disc image and cue sheet) or .pbp format (compressed).
