1.) How do I get the Victory Pose taunt hack? I've looked everywhere and I can't find it.
2.) Whenever I try to use magenta as invisible , it still comes out as magenta in game. How do I get it to be invisible??
As far as animations go, I'm not experienced in that area of Brawl hacking so I can't help you there.
But, for transparency, it depends what texture you are trying to make transparent. Use this as a guide for ASH: http://forums.kc-mm.com/index.php?topic=3329.0
If you are using BrawlBox, don't use magenta. Delete that section of the texture in Photoshop/GIMP so you see checkered white and gray boxes instead.
