Every Namco System 246 or 256 game I own, I have created an ISO of for backup, just incase the original disc were to be damaged or destroyed.

If your 256 is having problems reading a disc, put that disc in a computer, sometimes a pc dvd drive can read a disc that other drives cant read and you can just make a 1 to 1 copy without problems.

Since the Namco Systems use standard pc dvd drives, you can use just about any type of media from DVD-R, DVD+R, DVD-RW or DVD+RW. Using the rewritable discs is good if you are unsure if it will work, so you don't waste a disc.
