Oh hey! A couple things, if you don't mind. First off, you all are doing great, keep up the great work! Secondly, are you possibly getting this compatible with Retro/N64 mode? Thirdly, are you working on getting this for module so more character variety can be open or is that the BrawlEx team's job?
Lastly, I love to contribute, is there anything I could possibly do to help?
When N64 mode is released, it will have fully compatibility with BrawlEX.
Additionally, the victory theme issue will be fixed in the next official version.
As for the question about modules, these are the characters that don't even have beta versions as of right now:
*Yoshi
*Ice Climbers
*Wario
*G+W
*Pokemon Trainer Pokemon
*Kirby
Of those characters, the only ones I ever expect to do are the first three in that list: Yoshi, Iceclimbers and Wario. Kirby would be hell to do given how many character-specific commands he has throughout the game. G+W has a ridiculous number of articles, and the PT pokemon would not be fun to patch. So, I don't think that those three will ever have EXModules. The only one that I could see happening would be G+W of these particularly problematic characters.
Yoshi and Wario are feasible, and those are the first two I plan to do after I release the fixed beta modules. Fox has been finished, and DK just needs to have a minor bug fixed. The Ice Climbers could be done, but they may require gecko codes to work properly (the same goes for G+W)
