Dreamcast Boot CD HELP!!

[VT]

Could someone please let me know what is going on with my boot CD, I have the dreamcast model 3030 and have downloaded many Boot CD images in Nero and also CloneCD format.

Nothing seems to work, I have tried Blue and Gold CD's.

Am I burning the CD's wrong?
Are the images I am downloading no good?
Or is the model 3030 protected in some way?


Please could someone help me.

Cheers

Vince
