Batocera BIOS Pack — Overview and Guide
Best practices
- Keep a backup of your BIOS folder.
- Keep filenames unchanged unless documentation specifies otherwise.
- Use the correct regional BIOS if a game expects a specific region (e.g., SCPH-1001 for NTSC-U).
- Use official dumping guides when extracting BIOS from hardware to ensure integrity and legality.

| PS1 | scph5500.bin, scph5501.bin, scph5502.bin |
| PS2 | ps2-0200a-20040614.bin (and others, depending on region) |

Error 2: Neo Geo Games Show a Green Screen or Stutter
Cause: neogeo.zip is in the wrong location or is missing internal files.
Fix: Place neogeo.zip directly in /userdata/bios/ (not in a subfolder). Do not unzip it.
