Extremely short instructions: put this savegame on your Wii (if you have one on there already that you want to keep, back it up first!), start the game, walk to the “art room” (find some walkthrough on the intertubes if you cannot find it), look at the second character, enjoy!
Kudos to “roto” for finding the original buffer overflow, and many thanks for doing lots of testing!
I uploaded a new zip file that fixes a packaging error and clarifies the copyright and licensing. People who are “re-hosting” this file should update, read the license, and reconsider whether they really want to host this binary themselves; whoever distributes the binary needs to distribute the source code as well (loosely speaking, read the license for the exact terms!)
