FF6 Advance Hacking: The Summon Command

Okay.
Last one, I swear.
Does anyone here know how to make the Summon command work in the GBA version of FF6?
I know there is a patch to make it work on the SNES, but I haven't found anything for the GBA. The problem seems to be different as well.
In the SNES version I'm given to understand that it doesn't work because you can't aim it. In the GBA version it seems to not work because no matter how much MP you have, it always fails with the message "Out of MP!" or something like that. Does anyone have any notion of how that might be fixed?
