FEX-Emu allows you to run x86 and x86-64 binaries on an AArch64 Linux host, similar to qemu-user and box86/box64.

It has native support for a rootfs overlay, so you don't need to chroot, as well as some thunklibs so it can forward things like GL to the host.

It presents a Linux 5.0 or newer interface to the guest, and supports both AArch64 and x86-64 as hosts.

This project is very much work in progress, so expect things to change.
