Static recompilation of Majora's Mask (and soon Ocarina of Time) for PC (Windows/Linux) - Zelda64Recomp/Zelda64Recomp
Zelda 64: Recompiled is a project that uses N64: Recompiled to statically recompile Majora's Mask into a native port with many new features and enhancements.
The ROM in this case is only used for game assets, like maps, models, and textures. All the game logic in native code. This allows is to be easily modified to add in new features without trying to hack it into a 20 year old game/console.
It's a bit similar. However this goes a bit further than I understand those projects do. They're creating a game like the original. With this decompilation project, if you use the N64 compiler you will get a ROM which is 100% identical to the original.
