🥳 AltStore PAL, the first alternative app marketplace on iPhone, is available now in the EU for a nominal <€2/yr subscription price (to cover the Core Technology Fee), which includes access to @rileytestut’s Delta (which plays NES, SNES, GB/C/A, DS, N64 and Genesis games). It’s not fully open to third party devs yet, but there's a whole lot more to come in the future. Distributing your apps will be as easy as hosting a JSON file and pointing it at your notarized IPAs
I went through the purchase & install process for AltStore in the EU, and it's not really any more onerous than downloading a Mac app or installing a provisioning profile. One trip to Settings to ‘Allow’, and you can tap through the install dialogs in a second.
The install confirmation sheet, which provides metadata and screenshots about the app and its publisher, is kinda a nice thing to have? Honestly wouldn't surprise me if this system came back to macOS, too (if developers don't revolt)
