Do we know if these emulators will support JIT? JIT has always been prohibited on iOS (which is why there are no browsers other than Safari - Firefox and Chrome on iOS are just a Safari WebView plus a crappy interface on top).
Even when sideloading emulators, you only get JIT by paying for a special developer license or using exploits on very specific iOS versions.
Without JIT, sure, go nuts emulating the NES... But forget about anything more demanding than a GameCube, or using this to run a VM or something.
Actually Altstore has AltJIT which works on all iOS versions altstore supports but requires you to be connected to the same network as a computer running altstore.
UTM (which is based on QEMU) is already available on iOS.
So you mean iOS doesn't natively support JIT for App Store apps and requires hacky workarounds?
iOS natively supports JIT (by which we mean writable and executable memory) but Apple locks it down to only two use cases:
AltStore launches a debugger and connects it to your phone. Even though it’s not actually doing anything with a debugger, that’s enough to convince iOS to let your app use memory that’s both writable and executable (the key feature needed for JIT).
Without JIT you need to either resort to a slower form of emulation or do something creative.
If that’s how you want to put it, sure.
I was just pointing out that OPs list was incomplete. Also theoretically someone could include altjit in their app because the App Store guidelines don’t explicitly say you can’t (ofc this would most likely not work).
Sadly jail breaking is required after iOS 11
For what?
For for UTM
No I believe it also works with altstore (though I haven’t personally tried it).
Hmm. I’ll give that a shot.
