It is important to note that PSXonPSP660.bin is proprietary Sony code. It is technically illegal to download this file from a random website if you do not own the hardware it originated from (like a PS Classic or PSP).
RetroArch requires BIOS files to be placed in a specific folder called the "system" directory. You can find this directory in two ways: The specific options will depend on the core
(Best for ARM devices like the Raspberry Pi or mobile devices)

Unlike traditional BIOS files ripped directly from original PS1 hardware, this file is a to run PlayStation games more efficiently on the PSP’s emulation engine. Why is it "BETTER" for RetroArch?
