A decent offering would be a game cd image, be that bin, cue, etc. If you don't have that, then you can try burning it to a cd-rw but chances are it's missing components as birdy says. BTW normally we can't talk about piracy topics on this forum so ... I can't really offer any more help than that.

You could buy it. You could also look around for 2nd hand copies. I know around here there's 1st & 2nd hand game shop.
