Congrats? We don't care, no texture hacks of any kind are allowed, they can be distracting for people, bottom line, everyone will be using the same standard Brawl design.
This, I also take a lot of care into choosing stage textures and character overlays that are completely non invasive and non detrimental. I also make sure that they are clearly defined colors for teams as well.
Music hacks for stages are not permitted either but I don't see anything wrong with them on like the stage and character selection screens since the match isn't taking place. Up to Tant.
