To achieve an level configuration, combine psxonpsp660.bin with these RetroArch shaders:
The SHA256 checksum for this file should be checked if issues persist, as corrupted files will not work.
The data is clear: The 6.60 BIOS lowers the CPU overhead on the PPSSPP dynarec (dynamic recompiler), resulting in higher frame rates on the exact same hardware.

For years, the standard recommendation for PlayStation 1 emulation on lower-powered devices (ARM-based handhelds, Raspberry Pi, older Android phones) has been the scph1001.bin or scph5501.bin BIOS files.

The file named —a BIOS dumped from Sony's PlayStation Portable (PSP) “PS1 Emulator” (officially called POPS — P lay S tation P ortable)—is rewriting the rulebook.
By switching to psxonpsp660.bin , you effectively turn RetroArch into a powerhouse capable of running the PS1 library with modern polish and vintage accuracy. It is the single most effective "tweak" you can make to your emulation setup.
