What to know
- Anthropic has quietly restricted Claude from modding, decompiling or reverse-engineering video games and hardware like TVs, with no official explanation given.
- The restrictions follow a surge in AI-assisted game decompiling and cross-game ports, plus the PlayStation 5 jailbreak scene that enabled cross-platform play and backward compatibility.
- Legal pressure is part of the backdrop, including Take-Two Interactive's subpoenas against Microsoft and Discord over the viral GTA6 leaks.
- The new limits are broad enough to also block legitimate developers from troubleshooting and working on their own projects, drawing criticism over the scope of the clampdown.

The AI frontier companies want to control every aspect of your computing life going forward. This kind of thing will push more and more people toward local (on the user's machine) models. Even if you agree with Anthropic's logic here, the implications suck. https://www. tomshardware.com/tech-industry…

BREAKING: Anthropic's Claude AI blocks video game cloning and reverse-engineering, per Toms Hardware

Yup. But the vendor blobs being separate from the kernel is only the technical explanation. The larger context is how we ended up with an ecosystem where proprietary firmware, undocumented hardware interfaces and locked down boot chains can outlive the open source software they're supposed to support. There's an interesting historical dimension…

Redditor says canceled users deserve no sympathy
A commenter on the Tom's Hardware thread argues people using Claude for game cloning and reverse-engineering have no grounds to complain about being blocked.
“Honestly, if your reason to use them was to do shit like this, then I have no sympathy for you and I'm glad you canceled the account. It's the worst of the worst in AI. Like making AI slop videos etc... disgusting.”

Tom's Hardware details restrictions hitting legitimate developers
Tom's Hardware reports the new blocks on video game cloning and reverse-engineering are sweeping enough to also stop legitimate developers from basic troubleshooting and their own projects.
“highlights the irony of frontier AI companies that copied the world's information and art for their training sets and are now concerned with copyright infringement…”

»It always boggles my mind that instructions to LLMs come in the form of these inane, sometimes childishly simplistic commands? There is literally no more precise way to command an LLM?

Well think about it. A lot what happens is someone working very hard on a game and then someone comes along, decides they like what they see in the trailer and make some sort of clone that steals the original developer's thunder. Now sure we can go and explain how the clone is not as good and actually the real game behind it (the ruleset, the…

I assume data is as valuable as the goal it serves. They absolutely capture political information and facebook was a major tool used in swaying public opinion in the last few US elections.

We added two sentences to Claude Code's prompt on Opus 5.5 to steer it away from recreating someone else's specific game because using Claude to infringe IP is against our usage policy. Original games, genre games, and games built from your own designs and assets are meant to keep working. We'l...

Cloning a game with different assets isn't infringing IP, like “Doom clones” were a thing in the 90s. Anthropic is just making up its own standards and calling them the law because they don't want to be the subject of the next “Betamax case” brought by software IP holders.

Anthropic is going to watermark all text that comes out of Claude and give companies the tool to detect it, but not the users.Now they are also blocking specific uses of their models, with a blast radius that also affects people with similar but unrelated use cases.Add that to all the safeguards they already have added to their models for…

Reverse engineering is a legal and valuable skill. I didn't sub to Anthropic, but now I absolutely never will.

The only new piece of hardware I purchased was one of those unified memory cpus with 128gb. Everything else is repurposed hardware from hobby building the last decade.

I wanted to reverse engineer a win-xp era game with boring music and make it play my own selections--inherently a fair-use activity.

What is the difference from reverse engineering an app and saying "build me an app like Salesforce, here's their docs with all their features." The REA plugin just does the prompting for you, Claude will still build a Salesforce clone and do everything you want it to do it's just not as explicitly saying "rip off this app"

Very sad. I'm about 50% in taking the old Red Alert 2 and get to something that would've resembled the original source code.Given the rumors that the source code has been lost (and the fact that they open sourced the games before Tiberian Sun & Red Alert 2, and the ones after those), I felt like I was using the tokens for 'good'.We'll see when it…

I think that, excepting part of the HN crowd and linkedin, literally the only positive comments I've heard about AI have been related to game mods.I'm saying this as a completely orthogonal conversation to regularisation, ethics, etc. It's just amazing to see how little value these companies place in the general public's perception of them.Can you…

They really didn’t though. They put it in a client side modification to the system prompt. You can just rip it out with a proxy or a small local modification to your client, which Claude will be happy to do for you. They took a token step so that people would write these headlines in the hope it would stave off more negative attention in the video…
