Des moddeurs parviennent à décompiler Zelda 64 et publient le code en C

Pavant le chemin pour un portage vers d'autres plateformes et pour le modding

En 2019, des moddeurs ont publié une archive reconstituée du code source de Super Mario 64 (15 mégaoctets de code, comprenant notamment la gestion du personnage Mario - en langage C).
