Title: The Ultimate Guide to PS1 on PS3: Roms, BIN Files, and NEW BIOS Setup (2025 Update)
Introduction Want to play classic PlayStation 1 games on your PS3? Whether you have an original backward-compatible model (CECHA/B) or a later PS3 with Custom Firmware (CFW) or HEN, you need three things: the game ROM (usually in BIN/CUE format), a compatible emulator, and the PS1 BIOS. Here’s what’s new and how to set it up.

2. The "PS1 BIOS" – Still Required?
3. NEW BIOS Files for Better Compatibility
4. Step-by-Step for PS3 (HEN/CFW)
Troubleshooting: If you see "BIOS not found" error, rename the file to exactly ps1_bios.bin for some emulators.
The Sony PlayStation 3 (PS3) is a unique emulation machine. Unlike the PS4 or PS5, the original "Fat" PS3 models (CECH-A through CECH-E) contained actual PS1 and PS2 hardware chips. However, all PS3 models—even the later Slim and Super Slim—can play PS1 games via software emulation.
This draft provides a guide to obtaining and using the PS1 BIOS (ps1_rom.bin) extracted from the PlayStation 3 firmware for enhanced emulation and game compatibility. Overview: What is ps1_rom.bin?
Definition: ps1_rom.bin is the official PS1 BIOS emulator file included within the Sony PS3 system firmware.

| Item | Details |
|------|---------|
| Official PS3 (OFW) | No need for external PS1 BIOS — plays original PS1 discs and PSN downloads. |
| Custom Firmware (CFW/HEN) | You can add a PS1 BIOS for homebrew emulators or to launch backup .bin/.cue files via MultiMan/WebMAN MOD. |
| BIOS file name | Typically ps1_rom.bin or scph1001.bin (place in /dev_hdd0/game/PS1Uxxxx/ or RetroArch system folder). |
| Legal note | You must dump the BIOS from your own PS1 console. Downloading BIOS files is copyright infringement in most regions. |
