I believe that the files 319-368 and the files 1182-1259 in File7.olk are some kind of weapon properties data (size, sound effects, trail color, etc...). These are also found inside the SC3AE character model files as File9.pkg.
Actually, if I remember something I did a while a go correctly, it turned out that only File1 is different from the original version, so only that file is required for these movesets to work. That's all I know, though.
One more thing about Ivy and Yoshi: their movesets won't work even if you replace other characters' movesets with them.
I've also found out that only File1.pkg from AE File6.olk is needed for the AE movesets to work properly. The other three files don't change anything.
