I have found a lot of programs using vector $64 (via $00020064)
This is quite easy to find with an hex-editor (You will usually
find 3 times $00020064 : one to save old vector, patch the new and
restore the previous one !)

I did the same for patching the "core.o" : I still own an Atari Falcon
and I was using "Easyrider" which is a symbolic disassembler.
I now have it installed on my PC (at the office) and I am using it
with "Pacifist" which is a ST emulator for PC...
