I made one of these by cutting a piece of circuit 
board to the right size, then cutting the correct 
pattern into it with an Xacto knife. It looks pretty
horrible and has a tendency to cause crashes by shorting
adjacent traces together (it's hard to be very accurate
with the knife), but it does work. Didn't the ubiquitous
Mr Braner tell us about reconnecting wires to make the
cartridge port writable, some time ago?

The contact fingers on the cartridge are on 2 milimeter spacing.
