SameBoy

Émulateur v1.0

SameBoy est un émulateur Game Boy, Game Boy Color et Super Game Boy, conçu pour une compatibilité large tout en privilégiant la précision. Développé par Lior Halphon, il cible principalement macOS (avec un minimum requis de macOS 10.12), mais propose aussi des versions pour iOS et watchOS. Son code source est ouvert, ce qui permet des builds pour d’autres plateformes comme Windows ou les systèmes Unix.

Destiné aussi bien aux joueurs qu’aux développeurs, SameBoy mise sur une fidélité technique (debugging avancé, gestion des états de sauvegarde) et des fonctionnalités utilisateur (filtres de scaling, optimisations graphiques). Son interface intuitive et ses outils intégrés en font un choix solide pour explorer le patrimoine rétro sur Mac.
