Sadly, I have to agree. I was REALLY hoping the fix to the 8bit screen corruption on the RadeonHD4650 would have been included. Without that fix, all the RunInUAE stuff is completely useless to me. 
Why not use it on 16bit then? 8bit screenmodes lack proper color anyway (copper skies, aga stuff etc). Is it too slow on your machine if you do that?
