My PS2 quit playing the PS2 CD rom games. It will still play PS2 DVD rom originals, PS2 DVD rom backups, PS1 originals, DVD movies, DVD movie Backups, Audio CD's and Audio Cd's on CDR's. The only disc's that it will not play is the PS2 CDrom games (purple discs). I use the Flip Top swap combo, so I have voided any warranty I might have. It quit playing the purple discs before I got the Flip Top. Does anyone know whats wrong?
