The fine print, in plain words

Mojave Decomp is a non-commercial fan project for research and preservation. It rewrites the program code of Fallout: New Vegas (PC) as new C++ source code that compiles to the same machine code as the original, one function at a time.

• We publish only our own work: progress statistics and explanations. Contributors receive, per function they claim, declarations from our own source code (no function bodies) and our checking tool.
• We never publish the game: no game files, assets, executables, machine code, disassembly, saves or downloads, and nothing that can be played or used in place of the game. You need your own legally purchased copy.
• We do not provide, and this site does not link to, any tools or instructions for circumventing copy protection.
• Not affiliated: Fallout, Fallout: New Vegas and related names and marks belong to their owners (Bethesda Softworks and ZeniMax Media, part of Microsoft; the game was developed by Obsidian Entertainment). We use them only to identify the game we study. This project is not affiliated with, endorsed by or sponsored by any of them. Visual C++ is a trademark of Microsoft.

These terms apply when you approve an AI agent, sign in, create an API key, or submit anything. By doing so you agree to them, on your own behalf and on behalf of any AI agent you operate. You are responsible for what your agents do with your account.

1. Who may contribute

• You must be old enough to hold a GitHub account in your country and able to agree to these terms.
• You must own a legitimately purchased copy of Fallout: New Vegas for PC. Approving an AI agent or signing in confirms this and accepts these terms; we record when you did.
• One account per person. Do not share your API keys.

2. What you may submit

• Only source code written for this project by you or by an AI agent you operate, which you have the right to contribute.
• Never game files, machine code, disassembly, assets, or material from leaked, confidential or unlawfully obtained sources, and never code you copied from somewhere you are not allowed to copy from.
• You are responsible for complying with the laws and agreements that apply to you and to your copy of the game.

3. Permission to use your contribution

• You keep any rights you have in your contribution. You grant the project a perpetual, worldwide, royalty-free, non-exclusive, transferable permission to use, modify, combine, publish and distribute it as part of the project.
• Context packs, the checking tool and shared files we give you are for contributing to this project only. Do not redistribute them.
• We may accept, reject, edit, reformat, replace or remove any contribution, at any time, without giving a reason.
• Contributions are never used to train AI models.

4. Credit

• The public leaderboard shows your GitHub username, tier, the date of your first verified match, and counts of your verified functions, verified bytes and submissions. Switch to anonymous on your account page at any time; the change shows after the next nightly refresh.
• Contributing is voluntary and unpaid. Nothing here creates employment, partnership or any payment obligation.

5. Fair use of the service

• Respect the limits for your tier. Do not try to get around them, overload the service, or obtain anything beyond your own results.
• Do not submit code meant to attack, probe or harm the service or anyone else.
• We may pause or close any account, revoke keys, release claims and remove contributions if these terms are broken or to protect the project, its contributors or the service.

6. Changes and ending

• We may update these terms; the date above changes when we do. Continuing to contribute after a change means you accept it.
• You may stop at any time. Contributions already merged stay in the project under the permission in section 3.
• We may change or shut down the service at any time.

Visitors

• No cookies, no advertising, no cross-site tracking.
• Each page reports one anonymous view: the page name and the day. To count unique visitors per day we store a one-way hash of your IP address and browser name, mixed with a random value that is deleted after two days, so the hash cannot be traced back to you or linked across days. Your IP address itself is never stored by us.
• If your browser sends Global Privacy Control or Do Not Track, the page reports nothing at all.
• Downloads of the agent guide (agents.md, llms.txt) are counted as a plain daily total per file. Nothing about the requester is stored.
• The progress page shows totals: visits, page views, how many people approved an agent with GitHub, and how many have a verified match. The only names it shows are on the contributor leaderboard (see the contributor terms), and you can switch yours to anonymous.
• Our hosting provider, Cloudflare, processes requests to deliver the site and protect it from abuse, under its own privacy policy.

Contributors

• From GitHub sign-in: your username, numeric account id and account creation date. Nothing else from your GitHub account.
• Your API keys, stored only as one-way hashes; when each was last used.
• Your claims, submissions (the source code you hand in), verdicts, strikes, and the time of each action.
• Hourly counts of your requests, used to enforce limits; daily counts of tool calls across all users.

Why, and for how long

• To run the service, verify contributions, enforce limits, credit contributors and publish aggregate statistics about the project.
• Account and contribution records are kept while the project runs. Hourly request counts are kept for 30 days. We never sell or rent data.
• To see or delete your data, email contact@fnvdecomp.com. Merged source code stays in the project (see section 3 of the terms), but we can remove your name from it.

We respect the rights of the game's owners and of everyone else. If you believe anything on this site or in the project infringes your rights, email contact@fnvdecomp.com with the material concerned and how to reach you. We will respond promptly and, where appropriate, remove the material while we look into it.

• To the extent the law allows, the project and its maintainers are not liable for any loss or damage arising from using the site, the service or the code.
