Yeah, that happens to me sometimes. It's why I never finished Beyond Good and Evil.
I'm using pSX. The main advantage for me is that it took absolutely no effort to get working. :P No BIOs or anything to mess with. No matter what I did with ePSXe, I couldn't get it to work. pSX is pretty feature light, but I like it that way. If you're not having any real problems with your current emulator, there's probably no need to try pSX because it doesn't really do anything special.Currently I'm playing FF8 on a epsxe emu which for the most part runs aight, but if have a better one, hit me up, I'd love to try it.
