Stop being mean to newcomers, Cooba.

Anyway, welcome to the JCF. Currently, there is no way to edit Jazz 2 sprites. A community member, Pyromanus, made a program that he does not wish to distribute that allows one to view sprites, but that's as far as we've gotten.

Once the source code for JJ2 is released (if it is released, that is), doing something like this should quickly become possible.
