Help Black and white 2 pokemon sprite

Ok so I'm making a hack with mega evolution..but the animation during battle messes up my custom sprite..is there anyway to remove the in-battle sprite animations of the pokemon? Any help would be appreciated.

I never really finished refreshing my mind with animation work, but I think you should theoretically be able to find the NANR (.RNAN) and seek to where it says KBNA. The u32 after it is the size, so leave that alone. But the next two u16s are num_seq and num_frames, so change that u32 to 01000100.

Result should be:

4B 42 4E 41

NN NN NN NN

01 00 01 00

(Where NN NN NN NN was the previous size). Hope that gets you in the right direction!
