The GBA port of Final Fantasy VI did fix some but not all of the bugs the SNES version had.
One of these unfixed bugs is, that Siegfried's and Chupon's rages are still unobtainable because
the game does not keep track of that you encountered them and there is no formation that could 
show up in the veldt.

This patch fixes this issue.
Unused formations got altered so that they contain those two enemies and the game registers if
you encounter them in the colosseum. (Lazy coding, but it works, for more details look into "ragefix asm notes.txt")

Issues: Siegfried does not use his normal moveset and I have no idea why he isn't.
	If you sketch him, it shows all of his normal moves, he just refuses to use them. 
	(maybe he has no weapon equipped and CAN'T use them?)

This patch is designed for the european version of the game and will most probably NOT work with the US version!
Feel free to port it over though.

It works with the "sound restoration", "color restoration" and "General Violence" patches, it could work with other patches too, 
I didn't check and I have no intention to do so.
