Pony Fantasy VI Remake

Does it happen every time for said player? If not can they reproduce it? Have you attempted to trigger it yourself in order to validate their claim? I briefly tested your game here and it is seemingly working fine, so maybe there's some kind of conditions that will cause it to happen, but without being able to reproduce it to find out more what's causing it, it's anyone's guess. If you've used any patches that deal with Control I'd start there obviously, but if not, the first step would be seeing the glitch happen, which I am unable to do here thus far.

I've triggered it myself, yes. Both he and I can reproduc it. I've done no patches that affect Control. He made a vid of it. He later noted that Control seems to work properly if Brachosaur uses Disaster first. I checked Disaster against a vanilla rom and it's identical. Removing Disaster from the Control list does not change the glitch.

(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?

That was exactly it - he's at 65535 HP and MP. At 65530, it works. Thanks. Wow, that's... something.

@assassin: You have avoided the confused loon on this one... Good call!

This is where i'd ask if you also know the specific reason why 65535 MP will crush... i wonder if any other cap value can crush the game, like HP for example:
after all there's no monster which has 65535 HP in the game

Brachosaur has in my hack and (knock word) the Control glitch is the only oddity he's had.
