And yes, I've burned hundreds of games for my PS2 including rips so don't say 'Is your PS2 modded?' or anything like that. What did I do wrong with this though? It goes to a red screen saying 'Please insert PS2 format disc' even though all my other backups work fine.
I have a v7 PS2 with a no-solder mod-chip, and I'm having the same problem. I;ve tried CD-R/DVD-R and neither of them load. I've tried making different copies on different medias and still nothing. Can anyone help us???
