i've found working version of dungeon master (title screen's background is dark blue instead of black)
now the mouse work ok(slightly offset) and game works.in other versions (and previous ver of uae4all) mouse was everywhere and couldn't control it at all.

settlers, game i'd really like to work.. no success so far.
tried different versions (boot from disk 3 to save memory) but mouse is invisible.
on first screen(where protection is) it shows you system info. on my it says no realfastram available,not enough chipram. i remember playing this game on a600 and always had to run from disk 3 to save ram.

eye of the beholder crashes on title screen (lovely red software failure )

didn't try dune yet

in cannon fodder 2 and dungeon master when you move the mouse on the screen you can see stripe of jitter graphic at the bottom(cf2) in the middle(dm).

hope it helps a bit
