The only difference is that the 1001 bios if from US ntsc psx's while the 7502 bios is from PAL psx's.. The psx boot up screens may be slightly different.. Maybe the psx cd player screen too.. As for epsxe.. Sometimes PAL games work better on the 7502 bios than the 1001 bios..Originally posted by lordneeko
I have a quesiton. That has nothing to do with this forum. I was reading these messages and it popped in my head. What makes one bios better and different from another?
I had schp1001 and after reading this I DLed schp7502. I ran both and didn't see a difference....Can someone tell me what the differences are?
