- toast0 6y agoDreamcast uses El Torito for booting as well, I bet you could make that work too. Possible issues are that I don't know if the Dreamcast will inspect multiple boot images to find an appropriately labeled one, and I don't know if the other platforms will accept a bootable disc that's prepared for Dreamcast (must have at least two sessions, first session audio, second session data with el torito for booting)
