ARM64EC

A project called Madeira stacks Wine, FEX and DXMT to run x86-64 Windows games on a non-jailbroken iPhone. Thumper and ULTRAKILL are playable. Cyberpunk is not, despite the headlines, and the JIT catch is worse than it sounds.

FEX, Box64, Proton, DXVK, DXMT, Rosetta, MoltenVK. Every guide to running PC games on ARM throws these names at you at once. Here is what each one does, why they stack, and why every extra layer costs you frames.
