I just noticed that when I launch MACCEL3 manually after booting MagiC,
regardless of which of the 3 speeds offered by MACCEL3 I select, the mouse
pointer speed does not change. It's always much faster than on a real TT.
When running MagiC and MACCEL3 is in the AUTO folder, the mouse pointer
moves much faster than with an original TT. Whether fast-forward mode is on
or off does not make a difference. Without MagiC the mouse pointer speed is
normal.
The setup I am using for the original TT and Hatari is identical. It is the
same hard drive image.
