Your question is a little unclear. I assume that you are talking about taking an already ripped CD and returning it to full DVD. this would kind of be pointless. Find the rip kit that was used to make the rip. Look at all the files that it tells you to delete. Then use your original
to get all the files that you need to replace them with. It would go something like that. What I don't think that you are talking about is playing CD based games on a DVD. I recently did some research into this and there is a program that works. Unfortunatly the CD based games will not work on a DVD. There is some type of information stored on the disc thatidentifies it as a CD and therefore when it is played on a DVd it is rejected by the console. This program does work however for multiple games on one CD. Hope your answer is in there somewhere.
