Problems when burning .mdf .mds

[mini_p]

I got the game CT1 witch is in .mds, .mdf format.

I oponed the mds file with Deamon CD, then loaded everything up in a virtual drive.

Then I did a 1:1 copy with CloneCD, however, the finished CD witch is believed to be indentical with the .mdf didn't work on my DC.(got stuck at the dreamcast logo.)

is there anything to do with mutilsession when I burn the mdf???

thanks in advance
