Command Edit Upgrade patch [WIP] Alpha Patch Available

OK. I have some questions...

What event bit or whatever corresponds to Terra's Morph being unlocked?

What determines if a party member is only a guest?

EDIT:
I just upgraded the command edit routine.
Using the space I saved from optimizing the sustain status screen routine, I moved it up and added 2 minor features to give the whole thing a little polish.
1) When you press the A button to select a command that is not allowed to be changed, for now only Mimic does this, it no longer makes the 'click' sound.
2) Instead it makes the 'buzzer' sound and triggers the mosaic effect.

Here's the code:

Code:

One portion of Gogo's custom command setting in status menu
Gogo:  C3/2248: 20A622   JSR $22A6
       C3/224B: B90000   LDA $0000,Y (get character ID)

EDIT2:
Here is another observation I just made.
The text for the command in the 16th position actually IS drawn to the screen.
It's just in the wrong place.
I tried this with everything the way it is right now; optimized status screen + upgraded command edit.
If I mark Morph as allowed in usME, load up a save from the very end of the game having a full party roster, then the text for Rage is pushed down to the 16th slot when I open the status screen as expected there is nothing in the 16th position even though I can point to it as expected.
However, when I looked at the status screen itself, with the command list closed, there are the letters _ag_ in the lower left corner.
So all that really need to be done is make sure that the text appear in the right place.
Hopefully it doesn't prove to be too much of a hassle.

EDIT3:
I managed to get the commands to read from the default data instead of from the current data.
However, there is a bunch of text corruption caused by my changes.
I double checked the branches and jumps associated with the code for the routine at C3/5DC1, which generates the command list, and everything seems to be pointing to the correct places.
So I guess it's not reading the data the way it should.
Here's the code I changed & I'm attaching a pic of the messed up text:
