Hello, and thank you for your quick answer,

the problem I see is not with the register access (this is done for 
other devices) but with the graphics side.
I don't understand how VGA device draws the screen, (I guess is done 
using SDL), and I think this part is too merged with QEMU itself. Is it 
true?
