I noticed that InsomniaDx's and Squishy's morphlock patches weren't preventing me from pressing jump to unmorph, so I disassembled them in an effort to figure out why. Turns out they were checking for HJ boots instead of springball.

I translated code back into asm, fixed it, and commented it.
Here is that asm file. I have commented it so that changing which item it checks for, which button to disable(jump, shoot, run) and which solid tile BTS values it keys off of are easy to change.

Have fun with it!
