If you are trying to use this file and encountering errors (such as "BIOS not found" or games failing to boot), check the following:

Here is the unavoidable reality: You cannot legally download psxonpsp660.bin from a random website.

The BIOS remains the copyrighted intellectual property of Sony Interactive Entertainment. Distributing it without permission is software piracy, regardless of whether you own a physical PSP or PS1. The file is not abandonware; version 6.60 was released as late as 2014.

Many search results will lead you to ROM forums, Discord servers, or file lockers offering a free download. While technically accessible, using these downloads occupies a legal grey area at best. In the United States under the DMCA, and in most other countries under similar copyright treaties, downloading a copyrighted BIOS file you did not extract yourself is illegal.

Use the Beetle PSX HW core with a standard PS1 BIOS instead of trying to force the PSP BIOS.

Do not waste time trying to rename a different BIOS to psxonpsp660.bin; it will not work due to internal signature checks.

Before diving into the specific file, it is important to understand what a BIOS (Basic Input/Output System) does. In the original PlayStation console, the BIOS was the chip that contained the system's operating system. When you turned on a PS1, the BIOS was responsible for booting the hardware, checking the memory card, and loading the game disc.

In the world of emulation, the emulator software acts as the hardware, but it needs the BIOS file to "teach" it how to behave like a real PlayStation. It provides the necessary instructions for booting games and managing memory card saves.

Do not confuse this with a PC motherboard BIOS. In console emulation, the BIOS file is a low-level software layer that handles the console’s hardware initialization, disc reading routines, memory management, and often—crucially—the security checks for game discs.

For PSone emulation on a real PSP, Sony needed a way for the PSP hardware to interpret and run PSone games. Their solution was the POPs (PSone on PSP) loader, which is a built-in PSone emulator. Each firmware version contained a slightly different psxonpsp.bin file. Version 6.60 brought performance improvements and better compatibility, hence the 660 in the name.
