Been writing an Arm64 backend for Xenia and it's been such a delight learning a lot all at once. Implementing stack traces and unwind info for JITed code rn. Super undocumented Windows-Arm64 stuff that might be worth capturing or writing a little utility library for. Currently passing a bunch of unit tests. Not running any actual games at the moment due to some more subtle issues but getting there.
My next post is hopefully a screenshot of it actually running a game of some sort.
