i thinking of getting a original cd but will a copy or clone of the original work on a psx? i have a 5 year old and i know that he going to damage the original and if so what the best program to use to make a backup of it

Are you saying you want to copy the psxchange disc? If you are, it can't be done, you MUST use the original.

If it could be copied then there would be no need for it.. You could just copy the original games.

psx change is made in the same way that original games ae made, you cannot copy the protected boot blocks that the PSX uses to verify that the disc is an original thus PS-X change is not able to be copied using a standard CD-Writer
