i got it to work after searching google some more until i found someone with a problem almost identical to mine. im sure that my problem was that i was burning it too high since i put it at my maximum write speed of 16x, but i was burning the .mds file with the raw dao option. this is what solved my problem: "If anyone would like to add the Dreamcast configuration profile directly into their Alcohol 120%, open up the file 'AxType.ini', and insert the following code. Then burn it using the datatype called Dreamcast from the pulldown. It self boots and everything! Woo!!!
