As of a few days ago, Anthropic deployed its Claude Fable 5 AI model after the US temporarily restricted access. Now it has already been used to port the 2003 video game Command & Conquer: Generals – Zero Hour to iOS. It seemingly needed the source code, previous ports, and some human tweaking to get running.
This is according to the lead of product and design at Google AI Studio, Ammaar Reshi, who announced the port on X on July 4. Reshi says this specific port “had a chain of giants to stand on” because it used previous port efforts and modernisations. It is a direct fork of The Super Hackers’ Linux and macOS build of the game.

What is unique about this specific port is that it gets the game running on iOS specifically, and even comes with unique touch controls like tap to select, drag to create boxes, and long press to deselect. Even though it uses plenty of work by other teams, it seems like an impressive effort in itself.
If you’re looking to play the game for yourself on iPhone or iPad, you can do so with the GitHub page now. You will need your own copy of the game, though. Notably, it runs in the real engine and runs natively on Apple devices, so it’s not a glorified emulator.
Reshi talks about the porting process on GitHub. He argues that this is a human + AI collaboration, and not simply someone pointing an AI model at something and saying ‘go’. He says the code and debugging were done by Claude, but the playtesting was human. Reshi described problems like ‘the minimap is black’ and ‘I hear chirping,’ and the model would fix them. Reshi says, “Neither half ships this alone: one of us can’t write C++, and the other can’t hear the chirping.”
So how replicable is this for other games? As of right now, we don’t know. Reshi seems sceptical of being able to port Red Alert 2, as EA appears to have lost the source code for that game, so that’s already a pretty big hurdle to jump over. Even if companies manage to find their source code, many won’t willingly give it up to vibe coders to create ports, especially if that makes it less likely that gamers will buy future remasters or remakes.
And that’s before mentioning that AI models can scrape any information fed to them, and some game developers may not want to give that information away for free.
Reshi also claims to have fully exhausted a Claude Max sub in just 2 days, which means this project seems to have cost somewhere between $100 and $200 in tokens alone. And it seems like Fable 5 is the only model Reshi thinks can do the work. He reportedly tried it with Opus 4.8 and, even using Ultra Code, it couldn’t do the task. Perhaps tellingly, they made no mention of whether it had even been attempted on Google’s own AI vibe coding platform.
So if you have a few hundred burning a hole in your pocket, the source code for a game, and previous porting efforts to look at, it might only take a weekend to get the game running on your iPad. Simple, ey?
