Jap to english

I recently downloaded Jump! Ultimate Stars and language is real annoying:P. Someone gave me a link and he said that this translates the language. Does anyone know how to do this? PLEASE HELP :'(this is the wbsite:

It's a patch. Download the patch, drag and drop JUS rom onto it, and it should create a new patched rom, with a added P to it's filename.
