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
Yes, it is region free.
Wow, very interesting. Might look into this. Any ideas if this is possible on a hacked PS Vita?
“This”? Can you be more specific?
Sure, is dumping the PSX BIOS from a hacked PSP also possible on a hacked PS Vita?
Is there any way of going about tweaking a bios like this one to imorove performance?
I can actually confirm you can also dump this using a hacked PS Vita with the use of Adrenaline. I went ahead and tested it out today and it works brilliantly. Thanks for bringing this to my attention
