FEX-Emu is a free Linux usermode x86 and x86-64 emulator for arm64 designed to run PC games on AArch64 devices. The project is a joint development effort between SonicAdvance1 and skmp, both previously known for their work on Dolphin and reicast respectively (with other contributors as well).


Linux Linux ARM Official release


FEX is not a traditional emulator the way RPCS3 and Dolphin is. As a usermode emulator, it works similarly to qemu-user and Box86 which allow one processor architecture to run on another through translation. The difference is FEX uses the static-single-assignment approach for intermediate representation of code.

FEX was first showcased getting in-game on Counter Strike: Global Offensive in April 2021.[1]
