If you want to disable a move, you might want to check the .cmd file. Open it up in fighter factory. Find the changestate that activates that move, and null it.
Turn on the debug; look at the bottom left of the screen and do the move; record the state no that it says you're in when doing the move. This is what you're looking for in the debug:
State no = [Number of the state goes here]
Once you find that number, go to the command Like I said, and search for a changestate sctrl that has a "value" of whatever number you recorded. Then do this to that specific changestate:
Null ;changestate
