Method for making Super Jump codes in SNES?

[MathUser]

I'm trying to figure out how to make some super jump codes for these super nintendo and genesis systems. Without joker codes its kinda hard. I usually wind up with codes that make me fly up into the ceiling and I won't come down until I turn off the code. So what would be the best method be to find these kind of codes? Any help would be appreciated. Thanks.

I'm guessing, it'd work to breakpoint an address that made you fly up, and figure out from near the results where exactly the limit for jump height is. I've no idea how hard doing so might be, I've never tried it.
