Dreamcast .cdi files

System: DreamCast

I plan on buying a DC soon, and I want to burn some games. However, Vimm's Lair doesn't currently offer DC games in .cdi format (yes, I know it's inferior, but good luck finding blank GD-ROM discs). I think that, though a small contribution compared to, say, Wii U games, retro enthusiasts such as myself could benefit from .cdi files.
