What is a game decompilation?

A decompilation project reconstructs readable source code from a game's compiled binary. Contributors compare their code with the original executable until it produces the same result, which makes the game understandable, rebuildable and portable.

What is a static recompilation?

A static recompilation translates the original game's compiled machine code ahead of time into a native program for another platform, usually a PC port, instead of emulating the console while you play.

Do I need the original game to use these projects?

In most cases yes. These projects ship code only, not the game's art, audio or data, so you supply your own legally obtained copy. Each page states what a project needs to run.

Are these projects legal?

The code written by the project's contributors is licensed by them, but the original game's assets and code stay the property of their rights holders. Each page lists who licenses what, as stated in the project's own repository.
