« Vous pouvez compiler ces contenus en l’état et obtenir une ROM Super Mario 64 fonctionnelle », ont indiqué les modders. Des chaînes d’outils modernes comme gcc permettent d’y parvenir. D’ailleurs, des preuves de concept sont déjà disponibles.
Les modders expliquent qu’ils y sont parvenus parce que Nintendo n’a pas activé les optimisations lors de la compilation. La manœuvre permet pourtant aux éditeurs de jeux vidéos de réduire la taille du code source et d’obscurcir sa structure. Les développeurs de l’éditeur japonais ont plutôt compilé sans le flag -O pour obtenir le binaire que la console exécute. En s'appuyant sur cette omission, les modders n’ont eu qu’à lire le code assembleur et à réécrire les fonctions qu’ils ont par la suite passées au test jusqu’à parvenir à une ROM fonctionnelle.
« Cette base de code est un trésor à préserver à tous les prix. Il s’avère que si vous compilez votre ROM sans optimisations, il est très facile d’obtenir le code non compilé à partir de l’assembleur. Nintendo aurait dû vérifier les CFLAGS avant de publier les versions américaine et japonaise », ont-ils lancé.
La réussite de l’opération a néanmoins nécessité qu’ils parviennent à émuler une ancienne version d’IRIX afin de pouvoir faire tourner un kit de développement Nintendo 64 identique à celui sur lequel les développeurs de la firme se sont appuyés. IRIX est un OS Unix de la société SGI. Il est conçu pour tourner de façon native sur les ordinateurs 32 et 64 bits basés sur l’architecture MIPS.
Avec la publication de cette base de code, la cuisine interne devient plus aisée à appréhender pour la communauté des modders. En théorie, cette situation ouvre la porte au portage du jeu sur d’autres plateformes informatiques. En matière de performances, l’expérience peut s’avérer bénéfique puisque la disponibilité de versions natives permet de faire sans les émulateurs. En sus, il y a que les modders pourront déceler et corriger certaines erreurs de l’éditeur japonais. D’ailleurs des retours initiaux font état de ce que la compilation avec options d’optimisation permet d’obtenir une expérience de jeu plus fluide. Seulement, attention car le Japonais veille sur ses intérêts. Il y a un plus d’un an, il a initié une action en justice contre des sites qui offrent des ROM de jeux récents ou rétro. Il a fini par avoir gain de cause et ces derniers doivent lui verser 12 millions de dollars pour violation directe et indirecte de droits d’auteur.
