I assume it would be as simple as searching for the
address of the superjump poke (as low-byte/high-byte, of
course) in the code, and replacing it with 36477, and of
course substituting the correct values to poke into
those addresses when the poke is turned on/off. It
should be straightforward for anyone with a working
knowledge of machine code, I would
think.
