Diablo II on your iPhone, from your own Switch copy

What it is

Someone built a bridge so that Diablo II: Resurrected, including its Reign of the Warlock expansion, runs on an iPhone, iPad or Mac. It runs right there on the device, with full touch controls and a smooth 60 frames per second. It even adds new endgame modes.

The clever part is what it leaves out: the game itself. You bring the files from your own Nintendo Switch copy. The project only ships the bridge, with no copyrighted game data inside.

It topped a weekly GitHub trending roundup with 3,567 stars, which tells you how many people wanted exactly this.

Why it's worth a look, even if you don't play

Take away the dragons and this is a story about something you already own being stuck in one place. A game bought for one console, suddenly usable on the phone in your pocket.

Every business has its own version of this. Old files in a program you stopped paying for. A tool that only works on that one laptop in the back office. Projects like this are a quiet reminder that "it only works there" is often a technical problem, not a law of nature. They also show a respectful way to solve it: move what's yours, without taking what isn't.

Words worth knowing

• Compatibility layer: a translator that lets software built for one device run on another, without rebuilding it from scratch.
• Open source: the code behind the software is public, so anyone can read it, check it or improve it.
• Bring your own files: the tool gives you the machinery, and you supply the content you legally own.
• Native: running directly on your device rather than being streamed from somewhere else.

Something to think about

What's locked in one corner of your business that you'd love to use somewhere else? It might be more movable than you think.
