Are you sure this was not present before ? the last pixels of an 
overscan line are usually altered by the hi/lo stabilizer switch, and 
Hatari seems to display 2 more lines than most STF, but this didn't 
change since a while.
(DSOTS was part of my reference list of demos to add CE mode, so I'm 
pretty sure it works correctly)

I think adding correct cycle for each memory access should give 
interesting results. We'll see that later.
