Uhhh, no. I don't think you did. That'd be handy for some other stuff
actually. Can I build it with CodeWarrior 9 or 10? (I think that's the
latest Mac stuff I have...)

As is, I just used a disassembly and searched the whole thing for
occurrances of stuff like DB F8 (the DB could be wrong, I don't recall--
it's just the hex equivalent of "IN A,"). I can always just go look for
the opcode for IN A,(C)...

Source would be handy though if you want to throw it my way. In particular
I'd like to see if there are any RAM locations that aren't used (and
common) between the games... :-)
