emulators and other apps for the DC?

Well, after about 2 weeks of trying and wasting cd's i figure i need to ask for assistance. I have been trying to burn an emulator and roms onto a disk which the DC will recognize. It just wont work. I have tried and tried but the bloody thing isnt loading. i have the boot disk and i have used many methods including using mkisofs to make an image out of the existing files but still to no luck. Anyone have any ideas or know if this is even possible? Why make an emulator for the dc if it isnt going to work.... (i am talking about the snes emu and the gb emu. I have had success with neither of them.)
