[Djmack8000]

i've almost got my soul calibur up and running, and i've got all the good stuff i need (i think)

When i load up chankast, it loads the blue dreamcast logo, then says:

"this game dosn't support the a/v cable that is currently connected to the main console. Turn off the power and replace the main power"

i'm running the cdi image in alchohol 120%
and i dont know what is wrong...

HELP!
