I don't know if you are able to go from DVDR to CDR that easily (I think you can). But you need to get the LBA order right in order for it to boot correctly. The LBA order must be the same as the original game. I believe that should work..... (At least that's how I shrunk my PS2 games and got them to work! Gotta save space on my HDD ya know!)
