That’s the wrong GPU. You need to flash that with the Elsa 979GS BIOS. I have a thread here with instructions.
Thanx for the reply.

I have already reflashed it yesterday night, the issue is solved.
Btw, I still have 2 questions about minor probs :
I have noticed when I launch a game, there's always 1 credit automatically added. Is there a way to remove that (I use your latest 2.0 multi version) ?
A question about Attractmode interface for Attractmode users : how to fix the controls in menu ? When I remap joy up, down, right, left, the directions are inaccurate.
