Hi, I have been downloading .cdi files for my dreamcast games due to my dreamcast having a tendency to scratch the hell out of my original GD-Rom disks. Every game that I have found and burned has worked on my dreamcast except for one game, that being Sonic adventure. I am using your normal 700 mb CD-R disk to burn the games onto and all of the games boot up and run perfectly accept for this.
Here are the .cdi files that I have tried:

I am reading things about the original game being too big for an 80 min (700 mb) CD-R and that there was a .cdi file made by the awesome RDC team that cut the japanese voice clips and various other unused assets that cuts the game down to the correct size for a 700 mb CD-R disk. The issue is that I cannot find this file anywhere except for some shady asian file website where it is included in a torrent and I don't want to risk it.
If anyone has a working .cdi file please send me the correct way or somehow send the file, thanks!
