Hi,
As you might know, Hangover development stalled years ago waiting for the WoW64 support in Wine to complete. With Wine 8.0 (and even better with Jaceks wow branch) this is now done. In October I started to connect Qemu to that WoW64 support in my spare time and it progressed until I finally was able to publish some of that work today. It's still missing instructions and even some patches, but it should give a good introduction on what this will look like. In fact I started to get wowarmhw running, so I could do the first steps on a x86-64 machine to run ARM32 binaries. But exactly this part is missing for now as things changed since then.
So in case I made you curious, here's the code :) https://github.com/AndreRH/hangover
