I've updated what the specials are supposed to be, as of right now they dont move and idk why they freeze up but im pretty sure it has something to do with the if statements in the subactions tab, also how did you do the indexing thing? i know nothing about models/bones
I don't know too much about psa, but I'll look at what I can do in a bit.
As for the indexing, the FitPit.pac file has some important information in it pertaining to bone index numbers. Namely, when a character is grabbed/thrown, the bone that is "grabbed" is the HipN bone, and it needs to be a certain index for each character if you don't change the "FitCharacter.pac" file. For Pit the number is 12 normally... but you can change it. I used the program called Tabuu, but you can use BrawlBox now: Where you need to go after opening the FitPit.pac file is: FitCharacter > MoveDef_FitCharacter > Sections > data > Misc Section > [10] Bone References. The second number here is the HipN bone reference. (Other useful ones here are the first one, the ThrowN bone index, and the fifth one, the TransN bone index.)
A very helpful resource I found (and the place I learned to do this):

EDIT: Also, I feel like making hitboxes and stuff for a move would be easier if they have animations made...
