Take a peek at http://www.cling.gu.se/~cl3polof/kernal4.asm
The irq redirector is actually from stolen from the Ultima IV, but I
don't think Chuckles would mind (he sold his setup including all the
source in comp.sys.cbm a few years ago). The only kernal call that is
patched is setnam, as it'd fail if the name is located under the rom.
Umm, I think. It would on a C64, and I haven't actually checked the
Plus/4 kernal. I haven't patched the save routine - again, I'm not
sure how the Plus/4 kernal handles saving under the rom.

Sorry, didn't read the paragraph correctly, it works just like the
others.
