I know the full game does not work in JB mode but the retail demo pkg file runs (downloadable this website). I was wondering if you swapped any of the demo roms i.e sonic 3 with the files on a retail disc that you can't get in the demo if it would play the game without any errors or if someone added roms not available in the full retail version?

Unfortunately I don't have a blu ray drive to test but own the full version of the game so cannot test myself and I don't have the FTP software installed to look at the files. Just wondering if anyones tried this and if it will work or throw up some errors (checksum errors etc)?
