Very excited about this! But I’ve also been impatient and started using Eclipse for all of my Gameboy emulation over the last year.. it a PWA and uses local storage for game saves. https://eclipseemu.me/

I’ve been emulating DS games on my iPhone for a while with a web app pinned to my home screen. It warns to backup saves (and I have) but I haven’t had any issues yet. It lags a bit if my phone is in battery saving mode, but otherwise works flawlessly. Crazy that “old” but also relatively recent systems can just run in a web browser now.

Another very good web app emulator is https://afterplay.io. It also works very well within the browser or installed on the homescreen.

I’ve also enjoyed using desmume for DS emulation https://github.com/44670/desmume-wasm

What's a revoke? Why is it a problem?

Guessing here, but I suspect they are referring to the revocation of the enterprise signing certificates used by gray-market iOS app stores, since native app emulators could only be distributed that way until now.

It's whack-a-mole- the stores sign their executables with a new certificate, Apple finds out about it, revokes the certificate. When that happens, I imagine the software signed by that certificate will no longer run on the devices the software was installed to.

I assume they’re referring to when the App Store revoked everyone’s emulator apps. For Apple to break these they’d probably need to remove standard web APIs.

When you load an app on your own iOS device with a free developer account, that app will fail to open (as in be revoked) after seven days unless you refresh it from a Mac (or Windows system with AltStore or similar).
