I'm running Mint on my laptop. Couldn't say if SteamOS would use the same method, but I'll give it a shot.

If you have access to Software Manager within the Menu (Administration>Software Manager) run that. Then, in the search field type in "wine". Install the package "Wine" as well as "Q4wine" if that is available.

I hope this helps you! Sorry if it doesn't.

It seems to run fine via WINE. But yes, a native port would be great!

You're welcome! :)
