I need help with .sawnd files

[Raichu Girl]

So Im using geko os, I got some .sawnd files for diddy, ike, sonic, lucario, r.o.b, snake,and picachu, I named them how it should be and when I check the options of the game they work, but when I try playing as those characters the game freezes  .

I want to know if Im missing something or am I doing something wrong?

maybe file size is too big
file size od sawnd need to be similar of original
also format sounds need to be the same like mono or stereo
