need help

I don't think CloneCD is compatible with your burner. So some questions that might prompt you to a solution:

1/
Are you burning at > 4x? That can be a problem. Stick to 4x or slower. But you've had that advice already.

2/
Are you copying from an original or a proven backup? If there are no scratches nor read errors (Abort on Read Error) it's fine to copy a backup. That's also been covered in a previous reply, but we don't know if you've taken the advice.

3/
CloneCD isn't out of trial period or is properly licensed, isn't it?

4/
You do have a modchip installed, don't you? Looking back over your past posts you never answered that question.

5/
What is your boot method? Some detail might help.

Beyond the above points, there is no reason why your copies shouldn't boot. I'd assume the modchip to be properly installed.
