In response to questions by Evan Bauman, Ken Hancock and others...
MacLanding (a Defender-like shareware game for the Mac) uses
calls to GetKeyMap() to read key codes "directly" so that you
can (for example) fire, move and bomb simultaneously. The key
to detonate a smart bomb has key code 03, which is the enter key
on an old Mac keyboard and nothing on any keyboard since the Mac+.
Soooo... to patch this, run the game with a debugger trapping for
calls to GetKeyMap(), trace manually from there and look for things
that look like entries in a key map being masked and tested.
Well, actually, you don't have to. I did it this afternoon. Using
FEdit, search for the hex string 0010 6758. There should only be
one. The 0010 is used to mask the Enter key's entry in the key map.
Changing it to 0008 will make Backspace (Delete) the smart bomb key,
which seems more appropriate anyway.
Hope this is of help.
