The guy asked about changing the VGA fonts to allow a mouse pointer.
Hetz - the way those applications did the fluid movement of the mouse
pointer was by assigning four characters for the mouse pointer. If they
decided that the mouse should be over the that is between four
characters in a square (say:
ab
cd
)
They would replace the characters with the four reserved characters
(let's call them
12
34
)
Next, they would reassign the VGA font so that "1" will look like "a"
with the top left part of an arrow over it, "2" like a "b" with the top
right part of an arrow over it, and so on.
Hence, all DOSEMU need to do in order to be able to support these
applications is support changing the VGA font. As far as I know, this
works (never tried). Hence - noooo problem.
