Tekken Problems...

As Charlie mentioned, if there is a read error then the original is probably damaged and therefore no backup can be made.

You could try using Fireburner to make the image as it wont bomb out like CDRWin does when it gets to a damaged sector, instead it will insert zero's where it cant read the information!

This in turn will result in an image file containing some zero's, and as BOT-CK has mentioned a thousand times before, whats the point as no original PSX disc contains zero's, so you will end up with a backup that will fail when it gets to those zero's!

Your best bet would be to get an original that has no errors during the reading session!
