Elias moved the file into the /BIOS directory of his SD card. He knew the risks. Switching to this high-performance BIOS meant his old save states might break—a small price for digital purity. He hit "Reset."
While OnionOS recognizes the filename PSXONPSP660.bin natively, some users prefer to make copies of it and rename them to scph1001.bin or scph7001.bin to trick older emulators into using the superior PSP code. 3. Batocera Original PS1 consoles were region-locked
