Problem with dreamcast roms

Hello community, i have a problem with dreamcast roms/emulator..
I am using ChankastAlpha025, and i cant play anygame, that is because all the roms are considered as some music disk and when i go to the bios at the dreamcast emu it only runs the cdplayer not the game..
I also have the Dreamcast Utopia Boot CD but dont know what is for
Need help pls, thanks in regards

The Utopia is used to boot some games in an actual Dreamcast console.

ok, but besides that.. any1 knows any solution? im burning the .cdi image on daemontools, after loaded, the autorun opens it on the realplayer, i've tried Jet Grind Radio, Sonic Adventure 2 and Skies Of Arcadia

Turn off auto run and just try to open the game in your emulator.
