Pony Fantasy VI Remake

(this is a bit of a moonshot based on my memory of a GameFAQs post i read 13-15 years ago, that'll make me look like a confused loon if i'm wrong, or an utter genius if i'm right:)

lower Brachosaur's Max MP.  it cannot be 65535.  the game's code to generate the Control menu will be tripped up by that value.

also, what are the MP costs of Brachosaur's moves?
