A cheats + tools overlay for The Legend of Zelda: Ocarina of Time 3D, built on CTRComposer —
a raw .3gx overlay engine for the 3DS that renders its own UI with no game hooks.
🌐 Project page · 📦 Latest release
This wiki covers the technical/reference material that doesn't belong in the README:
- RAM Address Map — every memory address the plugin reads or writes: gSaveContext fields, the quest-status bitfield, inventory array, player offsets, the entrance-warp mechanism, the respawn struct, scene IDs, entrance indices, and the save-diffing methodology used to map them. The main resource for the community — reuse it for your own tools/research on OoT3D (USA), or as a worked example of mapping a packed save format.
- Building From Source — toolchain, build commands, and the gotchas that aren't obvious from the Makefile alone (spaces in paths, ThreadVars, the font-mapping quirk).
For installing the plugin, its feature list, and credits, see the repository README instead — this wiki is reference material, not the getting-started guide.
The engine itself — game-agnostic, no Zelda-specific code — is released separately as a blank,
buildable starting point for making your own 3DS .3gx plugin:
CTRComposer.
