# SM64 Scratch: rebuilding selected Super Mario 64 gameplay in Scratch

> SM64 Scratch builds a playable Scratch version of selected Super Mario 64 scenes from a user's USA ROM. Python decoders reconstruct textures, models, animations, collisions, and audio using recorded ROM offsets and conversion recipes; Scratch block patches implement gameplay based on the public decompilation. The initial beta includes the castle grounds, part of the castle interior, and Bob-omb Battlefield.
