I don't really get it. I try loading up PCSX2, but every time I try to run anything, the program closes. I've tried BIOSes from a few different sources, and finally from my friend, who got it running a bit before (though DMC wasn't compatible so he lost interest), but it's just not working. Any ideas?

To my understanding, PCSX2 has two different executables. Have you tried both?

Yes it does, and yes I have. One crashes slightly differently, but in the end, it still crashes.

What are your PC's specs? You need a really good computer to run PCSX2 but you have to understand that you still may not be able to run what few games do run at decent speeds. Kingdom Hearts and Final Fantasy X are the only games that I've seen that will run somewhat decently.

1.92GHz Processer, 1GB of ram, Radeon X800 GTO video.

Update: It started slightly working. Not sure exactly what I changed, but I can reach the basic PS2 menus. I'll tinker a bit more and see if I can't get something running.
