Well making a frame data thread takes quite a bit of tedious work. There are threads popping up for different characters as dedicated people create them (I made Ness, I know Ivy, Wolf and Zelda have them), but it will just take time.
If you want to find them yourself, you could go find a older version of BrawlBox, open a character skin file (Mario01.pac for example), right click on model data, hit preview all. then you need to load the fitmotion file on the left menu, and the fit file (the one without numbers) in the top menu. After doing this, the menu on the right will have a section called subactions, going into there will allow you to click and view any action that character can do.
Kinda confusing the first time, but after awhile it takes seconds to find a specific attack.
hope this helped
