XeniOS is a real Xbox 360 emulator for iPhone, iPad and Mac, and its own compatibility database has 340 games in it. That database also shows only 17 percent run well, and the headline titles were tested on an iPad Pro rather than a phone.

iCube shipped a rewritten jitless engine and a working iOS 26 JIT path on the same day. The 60fps claim going around has no source, and the project's own benchmarks are more interesting than the number anyway.
