Wine developers André Hentschel and Stefan Dösinger have been working on "Hangover" as a means of running Windows x86/x86_64 applications on 64-bit ARM (AArch64) Linux and Android or even Windows for ARM. They are out today with the project's first alpha release.
Hangover 0.4 is the first (alpha) release from this project for running x86/x86_64 Windows programs now on 64-bit ARM Linux distributions. Besides GNU/Linux platforms, Hangover can also run on Android as well. This also lays the groundwork for supporting Windows games on AArch64 using Direct3D/WineD3D though due to upstream Wine limitations that doesn't yet work on Android due to WineD3D not working off OpenGL ES at this time.
