I have had the same idea. I have a pioneer dvr-A03 burner. I just copied the GT3 game to a DVDR. I have yet to install the required neo2.2 needed to boot the dvdr. I do however have the GS1.9 needed to boot the dvdr. I still have to find a DVD game that has a larger TOC that the GT3 game. If you visit sgt-dan 's
webpage, you'll understand better.

If you find any better info on this, let me know too.
