i have burned 2 echelon images (jet grind radio and doa2 LE) and neither of them work when i pop them in my dreamcast. Is there something special you have to do to the images? i am using discjuggler and whenever i burn echelon games i get an error saying that my disc is invalid. So i burned the games anyway, and they didnt work. But i have burned other dc games that arent echelons with the same type of cd-rs and they work great. help would be appreciated.
