Working Wavedashing Code

[Yoku]

Can someone please send over a Wavedashing code that actually works? I tried three codes from here and they don't work and are also a bit buggy.

This one I got from the video does not work properly, wavedashing is bugging and the air doge crashes the game - https://www.youtube.com/watch?v=elRvelIMdAw&hd=1

This one crashes the game after the announcer says GO! - http://smashboards.com/threads/wavedashing-in-brawl-hacked-version.199260/

The third one I don't have its source, but say I double jump and attempt to wavedash, it just shoots you to the ground no matter how high you are

Maybe this is because the way I have my codes set up, I have Jump/Gravity Value modifications, Momemtum Capture Data, etc. Though I also tested with just the wavedash and the file patch code to make sure, but I still get the same results, so if anyone has one that works properly then can you please send one? I am willing to send over a .txt with all my codes if needed to.
Is it possible its not working because I am running on the Wii U? That being said I can't use a Gamecube controller on the Wii U.

Thanks!
