Changing the Command name

There are two codes here. I believe the code at C2 is related at replacement of commands in-battle. The code at C3 is related at replacement of commands out-battle. They have exactly the same two tables but they are different.

It may be difficult to expand the number of commands because of the special ones. After 0x1E index the game engine will use special commands as flags for special animations or situations. They have very specific code and they are far away from versatile. You can't erase or change them because the game engine uses them, generally in a very specific, twisted and unconventional way. For reference, I know the following special commands:

Code:

0x20 Stumble (Mog Dance)
0x21 Roulette (Roulette special effect)
0x23 Tackle (Umaro)
0x24 Throw (Umaro throws a person)
0x26 Dice animation

I believe there are other commands related to animations or special effects: Morph animation, Retort animation, regen, seizure and phantasm triggers, etc.
