When you use this BIOS in modern emulators running on Android phones, single-board computers (like the Raspberry Pi), or budget handhelds, you get a noticeable reduction in CPU overhead. 2. Superior Audio Synchronization
When Sony launched the PSP, they included a built-in, highly optimized PS1 emulator called POPS. To make games run smoothly on the PSP's mobile hardware, Sony developers streamlined the original PS1 hardware BIOS into a compact, efficient software file.
