Here you'll find modding tools, documentation and more for Zelda games.
Ocarina of Time text editor which supports (almost) all versions of the game, with a (mostly) accurate preview of what the dialogues will look like ingame.
Cadence of Hyrule map view and editor, supporting all versions of the game, including the Symphony of the Mask DLC. It is not feature-complete, and some map data might be lost when used.
Ocarina of Time and Majora's Mask UI modification made easy. Modify the UI with the click of a button... Or at least that was the plan.Unmaintained.
An almost fully documented list of the OoT save format. The OoT3D list is not as complete.
A whole bunch of information about the RAM in Ocarina of Time.
A whole bunch of information about the RAM in Majora's Mask.
A personal project of mine. It is no longer in development, but the source is available.
This mod will put your puzzle solving skills to the test and makes Master Quest look like child's play.
