-   -   New FS-UAE branches with updated emulation code from WinUAE (http://eab.abime.net/showthread.php?t=85313)

Please note; the winuae4210 branch has been merged into master. Before doing that, master was branched into fs-uae-3.0, so further 2.9dev / 3.0 releases will be made from this branch. 3.1dev releases will be made from the master branch.

Great work! Thank you!

I realize that this would be pile even more work on Frode's shoulders but on macOS there may be a chance that the Metal API exposes these kind of things?
I am not familiar with it so I have no clue if that is the case but since the API was pushed with game developers in mind, it seems likely that sync-status retrieval was included in some form.

This thread will soon be replaced with a proper thread for the new development series. I have of course taken noticed of the reported crash reports and will still be reviewing those.

It could actually be, but I can almost guarantee that I'm not writing nor directly supporting Metal. (I'm quite annoyed that Apple did their own thing instead of supporting Vulcan, or provide proper and updated OpenGL drivers).
