TL;DR
- ZeldaRET’s The Legend of Zelda: Majora’s Masks decompilation mission has reached 100%.
- The codebase now completely matches the unique title, unlocking mods, optimizations, and customizations.
- Different 100% decompilation initiatives embody Ocarina of Time, The Minish Cap, and Tremendous Mario 64.
After greater than three years of labor, the ZeldaRET workforce has completely recreated the codebase for The Legend of Zelda: Majora’s Masks. This can be a big achievement for the Zelda group, enabling not simply additional examine of how the code works, but additionally ports, mods, optimizations, and hacks for speedrunners.
Mission completion has been hovering within the excessive 90s for six months now, however ZeldaRET member darkeye made the official 100% announcement on Twitter earlier this week. They nonetheless famous that there’s loads of work to be performed, eradicating false matches and including extra documentation.

Nonetheless tons of labor to be performed (different variations, extra documentation, fixing faux matches, and so forth.), however an extremely satisfying finish to years of labor pic.twitter.com/GEUgjYU823
When you’re unfamiliar with decompilation, it’s the painstaking technique of reverse engineering the compiled code within the unique cartridge into readable code. Usually, this entails plenty of trial and error, writing and compiling code, after which evaluating the outcomes to the unique.
Importantly, the purpose of this mission is to not create a useful port of the sport. That will be copyright infringement. As an alternative, it creates an executable that may be mixed with a (legally acquired) ROM of the sport. It combines the brand new code with the copyrighted property like textual content, sprites, and textures from the unique sport. Different teams can use this to make ports, however the ZeldaRET group doesn’t wish to be concerned.
The N64 is notoriously tough to emulate, however decomps allow absolutely native ports.
That is notably vital for consoles just like the N64, which is notoriously tough to emulate. With an ideal codebase, native ports can run easily on comparatively weak {hardware} with help for widescreen outputs, greater framerates, cheats, savestates, and far, rather more. It additionally permits code historians to grasp why sure glitches occur in a sport.
Extra lately, static recompilation efforts have largely automated the decompilation course of, creating native ports in simply days or even weeks. Nonetheless, this skips the step the place the code is readable by people, so optimizations and mods are harder to implement. That is how the current Android Majora’s Masks port was created.
Earlier titles with 100% matching decompilations embody Tremendous Mario 64, Ocarina of Time, and The Minish Cap. The ZeldaRET workforce is at present engaged on Twilight Princess, Skyward Sword, and Breath of the Wild, however they’re years away from completion.
