Well, I do not know the SUN format. Maybe should I have a
look to know how bytes are arranged. The reason I ask
something about it is: How someone could code something
for MiNT using device drivers, if there is no doc ? (Is
there any ?). I started writing a XBIOS (video) driver for
SDL (http://www.libsdl.org).
And I would like to handle keyboard and mouse using
MiNT device drivers (because BIOS functions do not handle
the mouse, and I do not want to make something too machine
dependent). And I do not want to code something hardware
dependent (i.e. where assembly is required). It is a bit
hard, but it may be interesting to do.
