Can't get DreamSNES to Selfboot, or boot at all.

Need some help. I used these instructions:

Any help is appreciated.

edit: I just realized I used a CD-RW. Is that the problem?
edit2: yeah, I'm an idiot. Got it working.

DON'T use CD-RW's, they don't work on a non-modified Dreamcast.
Use CD-R's and the emulator will work ;)

i get myne to work
