| Requirement | What to Do | |-------------|------------| | | Ensure your PSP is updated to 4.00 or later. Firmware can be verified in Settings → System Settings → System Information . | | Homebrew Loader | Install a loader such as M33 Launcher , PSP Launcher , or Pro CFW (if you already have custom firmware). The loader lets you run unsigned ELF files. | | PS1 BIOS | PSXONPSP requires the official SCPH‑1001 (or compatible) PS1 BIOS file ( scph1001.bin ). This is not supplied with the emulator. You must dump it from a PS1 you legally own. | | Storage Space | Allocate at least 30 MB on the PSP’s memory stick for the emulator and a modest number of ISOs. More space is needed for larger game libraries. | | Legal Copies of Games | Only load ISO/CSO files that you have the legal right to use (e.g., backup copies of discs you own). |
