It was always tricky to emulate *nix on proprietary OSes. But
emulating proprietary OSes on Linux does actually work a lot
better. Look at WINE, which has progressed to the point where it
can be the basis of a successful shipping product (the Steam Deck)
that lets users run Windows games without Windows. That works so
well, it puts true Windows-based handheld competitors in the shade.

 
You mention Wine, but do you know what you are talking about?

Just look at the success of the Steam Deck, and you’ll see.

What went wrong?  Clearly VSI hit some difficulties.  Public information
indicates that work on compilers took more time than expected (and that
could slow down other work as it depends on working compilers).

Weren’t they using existing code-generation tools like LLVM? That should
have saved them a lot of work.

No, the sheer job of reimplementing the entire kernel stack (including
custom driver support) on a new architecture was what slowed them down.
And the effort should have been avoided.
