Actually, I didn't meant a function for querying the HREQ line, but a
function that is called when the interrupt should be triggered.
But never mind, I've figured it out on my own. Now the HREQ interrupt
should be triggered right. However, Graoumpf tracker still is not
working right yet, it crashes for me when I try to load a .MOD file.
