of course it only takes six minutes to burn because a cdrom can only read the first section of the gdrom, you need to understand the architecture of the gdrom,
it contains the first set of data and then the rest of the gdrom has the game data which doesn't appear to the cdrom on a computer so the cue sheet that you are generating is just that first bit of data and thats all,
you cannot burn from cdrom to image of an original dreamcast game,
you need images or a serial cable to pc to rip the data yourself,
search a little on the board and the answers to your questions will probably be answered quicker then waiting for responses
stop burning coasters you will only burn coasters if you do what your above mentioned post indicates, and if anyone told you otherwise that it (cdrwin) can rip a gdrom then they are on crack
