iOS 16 stopped the GBA emulator from running. All the emulators except GBA were running as Retroarch cores. I decided this was a good time to switch from standalone mGBA to the Retroarch core as this ran well on iOS 16. 

After this a few people were having issues running games. I couldn't reproduce the issue. It turned out people had uploaded their games in zip archives which Afterplay didn't support but the standalone mGBA build did so they would run.

I figured out that that was the problem and have added in zip support for all consoles.

I don't recommend using zip archives though as sometimes they can have multiple versions of a rom in an archive. In this case Afterplay will just run the first file. 

You'll need to quit and open the app twice to get the new version :)
