Windows on Arm64, x86/x64 emulation

[DavidXanatos]

I'm wondering how the x86/x64 emulation on arm64 works, is the image loaded to memory the x86/x64 original and there is just a transpiled arm64 shadow copy, or is the code transpiled before and the loaded image is arm64 only.

I don't have any arm hardware yet, but am already thinking about how function hooks in x86/x64 emulated on arm64 would, or maybe wouldn't, work.

Anyone here who already has some experience and could shine some light on it?
