If you own Mario Superstar Baseball, congrats! You now also own a copy of the song Letters by Hikaru Utada @utadahikaru This 2002 song was just discovered hidden within the files of this game, never noticed for 21 years until now. I guess a Nintendo developer was a big fan

Here's some MSSB Debug mode screenshots! Something to note, the menus work but shipped with no text, so we coded in our own text, so this isn't exactly what the developers saw, but still fascinating!
