> I wonder if he's not talking about changing the bios on the real thing,I mean on a real PSX.
No need to wonder, Raziel, just read the topic, LOL :smash:
Anyways, when I was trying PSEmu Pro, I had a game called Descent Maximum and it hangs at certain point whenever I use 1000 bios, and doesn't hang with 1001. Although I didn't try this with ePSXe, which I use 1001 most of the time.
Most people say there's no speed difference, but I haven't experimented with it. But in terms of compatibility, it's very possible certain game only works with certain BIOS, so try a few if your game doesn't work.
