is there any way to play backup ps2 games on computer

yeah, but u can still do the swop trick without chipping your psx can't u? You just remove the white lock disc already in the machine and place it on top of the disk and if u do it that way then the games need to be patched ... or so i was told =p

P.S the description above is a little brief, but i know there is quite a bit of timed swapping needed when doing it that way.
