Humm... but this still won't work for PSX game discs right? Since they
have a bad checksum, a standard burner can't write them back out, because
it will correct the checksum?

What I don't understand is, why can't someone write a program that will
write the back check? I used to have a floppy disk copier for the Mac
that did something similar. If the source disk was damaged, it would
write the damaged data to the destination disk (the software was SUPPOSED
to do that, it was to let you duplicate bad disks before running things
like MacTools on it, in case it didn't work, you could dupe it again, and
try something different)

Alas, that software was for back in the "Classic Mac" era, and no longer
runs (nor has any idea how to write to a CD)
