I posted a bit about this in the other thread but i dout anybody noticed. Recently it has been discovered that the PSP JP 1.0 Bios units can run unencrypted code from the memory stick using a hacked bios update loader. I have not been able to get an elf to work yet but today a demo was released that works (I verified it my self this morning). So if you have a non updated JP PSP, you can copy the demo over and check it out for your self. Just go here http://anon.ug.to/sec/index.html Src - http://forums.ps2dev.org/viewtopic.php?t=1570
