I actually tried to do this in DiscJuggler 2 also. I know have a collection of 10 coasters while attempting to making the utopia boot cd.

Here's what I'm up against:
cdloader.cdi - utopia image
mitsumi 4x/8x (that 4208te model or whatever)
discjuggler 3, burning with advanced setting: mode 1

currently, each time i put a burned cd in (just the boot cd) i see the music interface of the dreamcast, "track1, "0:06"

any advice on what i'm doing wrong?
