I have been giving this a test drive, and have come up with a problem
with it.  Others who have used it may be able to shed some light.

The two sample education packages I've got to try (Aztec/Masterworld
and PicFile) both exhibit the same fault - when writing to the screen,
sometimes the emulated pixels (big blocky things by Amiga standards)
are being put at the wrong row address.  The effect is that a
line of text is cut along the half height and the two halves swapped.
Quite simple upper case words are just about undecipherable!  It also
may do a second order scramble - these swapped rows are swapped again
with other rows.  I think that is what happens, sometimes with multiple
lines you have great difficulty matching the pairs.

From my sample of two, I can't tell if it is bad luck or generic
problems with the emulator.
