Vampire Chronicles (DC) No picture only sound, plz help

I just got vampire chronicles (DC) selfbooting and i get sound but no picture im running it on a pal dc with a scart lead, does it need an RGB fix, ive looked but i cant find one, any suggestions. i tried using my pal rf unit and it works but the picture is totally crap and the sound is really fuzzy

yes it needs a RGB fix
but there is no patch for .cdi images
so give it up or play with a RCA cable.
