  • Kuribo64 forums: Originally, Kuribo64 was the place for Galaxy modding. If you are in for another time travel, consider looking through the posts. Keep in mind that the information you are going to find over there is very outdated and not accurate anymore.
  • Petari: A work-in-progress decompilation of Super Mario Galaxy 1 that also serves as a documentation of the actual game.
