yes all fighting styles/animations are found in this file yea,
...as far as the review goes i've had a sneek peek and its possibly changed by editing the text of the punch you wish to change, maybe this is how its done? having looked through the whole .img file it looks likely that the bbgun could perhaps be enabled fully aswell using the same method, that would be pretty cool if thats the case and this untested method is true, anyway good luck with this
