Vampire Chronicle RGB Patch Problem
 

I first burned with DiscJuggler3 Vampire Chronicle. All was fine with one big exception : I had only sound !!
Since my TV/Dreamcast are PAL versions, I thought that all i needed was a RGB patch. I found it and applied it on the .cdi image (as said in the nfo).
But after re-burning again, the game is not launching anymore ! (the machine sees it as a music cd) ...

Has anyone got the same problem ?
And, is there anyone knowing a solution ?
