I recently discovered how to back up my PS2 games using CloneCD. The first game i tried, alien vs. predator extinction worked fine, no problems. I'm trying to back-up Tony hawk underground and nhl 2004 now but the CloneCD, and the computer for that matter, seem to be unable to read the discs(?) Is there any way to back these games up or is it impossible? I play my back-ups using CD-Rs and a non-soldered mod-chip aswell, so i can only do swap trick.
