VGA Box

Hi,

I was wondering if anyone out there could lend a helping hand.

I was wondering if burned DC games work on a VGA Cable. I recently bought a cheap 3rd party VGA cable and I tried playing I would boot up the Utopia Disc but it wouldnt allow me. It said something like "this output cannot be used".

My question is will self-boot games work on VGA?? or they have to be the official product????

thanks
