Experimental wow64 mode issue Wine Arm64 failing to load ntdll.dll

Now thanks to the hard work done on this issue report:
https://bugs.winehq.org/show_bug.cgi?id=52715 I can now compile for Arm64

I just want to report that binaries that use the experimental wow64 mode will
fail and fail to load L"\??\C:\windows\syswow64\ntdll.dll"

You need to build the i386 arch, and then install a PE build of the FEX
emulator into the prefix. Presumably this will be handled by packagers at some
point.

Ah okay so how do I do that? I've compiled FEX but I think I might be running
into a pagesize issue there also

As a test could I copy the needed files from my PC and drop them in to where
they are needed?

You can copy the FEX dll (libwow64fex.dll) into the windows/system32 directory,
and specify the dll name in the HKLM\Software\Microsoft\Wow64\x86 key.

Your Wine also needs to be built with i386 support, i.e. configure
--enable-archs=aarch64,i386.

I would add that documentation into the readme for compiling wine for Arm64.

Alrighty so I got Wine compiled properly but I can't find proper documentation
on how to compile Fex and get the dll files compiled, I found some
documentation on their wiki page but I don't know if it's outdated or not since
it's got different compiling instruction it doesn't recommend using

Currently I have the current git version of box64, I have copied wow64 and
replaced the folder, compiled wine from git and added that dll file into the
windows/system32 directory
as well as added the registry key tho I have no idea if I did it right and
getting a different error so that some progress.
