I just found an entire ROM editor for Earthbound/Mother 2. With this little sucker, I can edit everything, including event Flags, text, PSI names, and even tilesets for specific areas! I have also found another program to edit PSI animations. The page for these downloads is located here.
Some examples of the use of this tool can be found here.
