making a bootable cd

[crispy]

In which case mate you're probably screwed as you only have the files (and maybe not even any hidden ones) on the cdr, and not any info from the disc which may be part of the protection mechanism.

And I'll repeat what I said for the cheap seats!!

I can't comment precisely cos you still haven't told me what burner you have and what game it is!!
Kinda hard to give help if I only have limited info about the problem.
