: Some emulator cores, such as Beetle PSX or PCSX ReARMed , utilize this file to better handle multi-disc games that have been converted into single .PBP files.

It sits in a folder, unassuming. A few hundred kilobytes. No icon, no fanfare. Just a name: psxonpsp660.bin .
cores) support this file because it often provides better compatibility and faster boot times for certain games compared to older BIOS versions. Legal Status:

Emulators require a console's BIOS to accurately replicate hardware behavior (initialization routines, CD handling, system calls). Some emulator builds or plugins are written to look for a particular filename and checksum; psxonpsp660.bin is one such expected filename for certain builds.
