there's a software out there, which claims to be an emulator capable of running ps2 games on pc
it's called pcsx2, what i want to ask is if it could run 1000LL games (copied discs) and what are the steps in order to make it work ?
Yes you can use the copied discs.
You will need to rip the DVDs into ISO files and the pcsx2 emulator can play them.

The guide posted above is very useful.

you can play without ripping them also, jsut insert that 1,000 disc and play, though its not that good, you have to change million settings for different games, and ts slow, graphics is weird also,still better than nothing
