Backups wont play. What could I be doing wrong?

[yunakagurazaka]

I've been using CloneCD to make backups for the passed year or so. and they have all ran fine in Virtual Game Station. Now, I just got a GoldFinger Cart to play back ups on my PS, but they will not work. I tried using Cloney and burning some games again, with its settings, but they still do not work.

Is it perhaps the discs I use? I'm not sure how picky the PS is about the media. I'm just using ones from Office Depot. I am also using a Ricoh DVD/CDRW MP9120, if that helps anybody.
