how to rip i don't know and i think it is prohibited to talk about this here. but i'll warn that isn't so simple... and this disc is a DREAMSNES, which is Super Nintendo emulator for Dreamcast. cool it isn't? i had one with my old dreamcast hehe... actually i know sites that have these emus like dcemulation.com (i think). perhaps you need to search for any post about how to rip gds...
