The ultimate way to play PlayStation 1 games on RetroArch is by using the psxonpsp660.bin BIOS file. While RetroArch supports several BIOS versions, this specific file is widely considered the gold standard for performance, compatibility, and stability.
3. Cleaner Setup
RetroArch can be finicky about file naming. Using the PSXonPSP660 file simplifies your system folder. Instead of a pile of confusing .bin files, you have one reliable workhorse that just works.
| Game Title | BIOS 5.00 (Old) | BIOS 6.60 (BETTER) |
| :--- | :--- | :--- |
| Tekken 6 | 45-50 FPS, audio crackling | 60 FPS stable, clean audio |
| Kingdom Hearts: BBS | Crashes on final boss | 100% playable |
| Syphon Filter: Logan's Shadow | Input lag at 2 frames | 0 input lag, V-sync ready |
| Homebrew (Emulators) | Fails to launch | Flawless execution |
Why People Say It’s “BETTER”
| Feature | Psxonpsp660.bin | Original PS1 BIOS (e.g., SCPH1001) |
|--------|----------------|--------------------------------------|
| Compatibility | Excellent – fixes many game glitches | Good, but some games have timing issues |
| Load times | Slightly faster (PSP optimization) | Standard |
| Audio sync | Better – fewer crackles in some games | Can drift in certain cores |
| Copy protection checks | Handles anti-piracy better | Some games refuse to boot |
| Performance overhead | Low – works great on ARM/RPi | Slightly heavier on old hardware |
Verification: Go to Main Menu -> Information -> Core Information. Scroll down. You should see "PSP BIOS (v6.60)" marked as Present.
Naming: Ensure the filename is exactly psxonpsp660.bin (all lowercase). Core Selection: Open RetroArch and load a PS1 core (e.g., Beetle PSX HW). Go to Information > Core Information.
