PSX BIOS from PSP 6.60 optimised to play games more smoothly: but how?


With this BIOS, first two screens are just skipped. You can just hear the sound from the second screen. BIOS Dump 2.6 identified the BIOS as a NTSC-J BIOS. My PSP is à European one. I used it to run a PAL game on Mednafen. So I think it’s region free. I just copied the file three times in « system » folder and renamed it scph5500.bin, scph5501.bin and scph5502.bin
