I'm not new to emulation in general but I am new to psx emulation. Anyways, I just downloaded ePSXe v. 1.2.0. I tried to configure it up so I could play some games and everything was fine until I had to give a *.bin file for the "bios configuration." I tried to find info all over the net but I just can't find anything to do with *.bin's and *.iso's. I noticed that it is illegal to give them away or link to a site that has them so I'm not going to ask that. What I am going to ask is 1)What exactly are they? 2)Do I have to "write" my own? 3)Why are they neccessary? and 4)Why can't I find any information on them ANYWHERE? Please fill me in A.S.A.P. I really want to play PSX games on my computer as quickly as I can. Thanx.
