Ah ok, I see the problem, I wasn't shocked by the color problem, I thought 
it was a result of VDI in general.

It's true colors are not inverted with hatari 1.1.0, but I don't really 
know the cause. I tried to change only interrupt handling with latest 
video.c, not colors.

Maybe Thomas has an idea ? An entry in HBLPalettes[] that would not be 
correct ?

Very strange, you mean just the fact to return from Video_Sync_WriteByte 
when bUseVDIRes is true ?
