About

1. A project is a repository: its URL, lower-cased, with any file path removed, is the key. One repository of many disassemblies is one project with many games.
2. A game is a title a project reconstructs. A game usually has several projects (a decompilation, and a port built on it), and an engine project has many games.
3. Every repository is looked up on GitHub for its stars, language, creation date and last push. A renamed repository is folded into its new name. A 404 or 451 answer marks the project removed.
4. A decompiler, emulator, library or curated list is a tool and is left out of the main pages unless asked for.
5. A project's title is the game, with the project's own name in parentheses when it does not say the game: "Super Mario 64 (sm64)".

• Matching decompilationA decompilation that compiles back to the exact original machine code.
• DecompilationReconstructs C or C++ source from the compiled game.
• DisassemblyMachine code turned into labelled, commented assembly source.
• Static recompilationMachine code translated ahead of time into source for another platform, without recovering the original.
• Native portRecovered or recompiled code adapted to run on another platform.
• Compatibility layerThe original executable, run through replacement platform services and graphics translation.
• RewriteThe game rebuilt in another language or architecture, informed by reverse engineering.
• Engine reimplementationAn engine written anew that runs the original game data.
• Fan remakeAn independent recreation, possibly with a new engine, assets or gameplay.
• Reverse engineeringResearch into formats and behaviour, short of runnable source.
• Leaked buildA port built from a leaked development build.
• ToolA decompiler, toolkit or list rather than a game project.
• UnclassifiedNothing recorded about how the project works.

• Active: Pushed to in the last twelve months.
• Inactive: No push in twelve months.
• Archived: Archived on GitHub.
• Removed: Gone from GitHub at build time (deleted, private or taken down).
• Not checked: Not on GitHub, or not yet checked.

Where a reviewer rated a project, the level runs from 0 to 5. Where only a yes/no flag is known, the project shows "AI-assisted".

• 0 · The maintainers state no generative AI was used.
• 1 · AI used for research or documentation only.
• 2 · AI used for minor, non-critical code.
• 3 · AI assisted on parts of the code, under human direction.
• 4 · Most of the code is AI-assisted or AI-generated.
• 5 · The project credits an AI agent with the work.
