Once the GD is ripped, how to boot it??

Hello, I just ripped the Sonic adv GD to my HDD, and downsample all the adx & afs I can, so that the whole size of the files are under 650 MB. I burn a cd with the same name as the GD (something like sonic_adv) and try to boot it via the utopia DC loader. The loader actually try to boot the game (I see the picture of sonic spinning on a cd) but after that...nothing... So, is it possible to burn a cd and to boot it via utopia DC loader? Have I to selfboot it via the echelon's tutorial? Is there something else?
Thanks to you if you read it, and if you can, help me ;-)
