If you're interested, I wrote a tracking program a few years back, which is
a bit like SnoopDos. It does a lot of patching of DOS routines. The source
can be found at:
http://website.lineone.net/~mechanismx/systracker/SysTracker_src.lha
Might be useful as an example. The files you'll be interested in are
st_patches.c and st_patches.asm. The actual patching is done in C, where
the patches themselves are in assembly.
Note: Disable PatchControl beforehand, if you're using it. The two seem to
conflict.
