can ps2s play copied games and if so how

PS2 can play copied games if a modchip is installed. You need to pay attention to PAL/NTSC issues if you play import backups. Please go to www.megagames.com and www.playstationmods.com for the full works on how to do it. You could also go back over this forum for advice. I'm not sure too many people are going to give detailed replies as this comes up over again and all you have to do is the research I've described.

Good luck
