The .cdi doesn't work

[Joe1234]

I tried to burn Sonic Adventure, but DiscJuggler said that the .cdi had an error or something like that. It asked if I wanted it to try to fix it, so I click yes. It burns, and then when I put it in, it won't load past the Dreamcast logo.

This happened with Quake 3 as well. Those two CDs were ruined, so I tried a third game, Skies of Arcadia. It once again gave me this message, so I turned back and now I'm asking for help. Some games don't have this problem, but others do.

I assume this means that the game's .cdi is 'scrambled' or whatever, but the stickied topic isn't helping me at all with how to fix this problem.

Lastly, I hope this is allowed here.

edit - bonus question

How do I change this to a working .CDI?:

Yeah, such talk is not allowed here.

You cannot get it to work it because it's piracy, and we don't support it. Go out.
