Steam has a new windows emulator for linux called Proton. (x86)

Steam has a windows emulator in their program now so their steamdeck can run any windows game.
I found out about it by accident, and ended up playing SEGA Model 3 on my RetroPie system using the supermodel emulator trough steam.
Perhaps it is possible to bypass steam to use the emulator but for now these are the steps I took to get my supermodel emulator to work.

Install steam, if on ubuntu just look for it in the store.
Then i added it to retropie by making a sh file in ports with the following code: #!/usr/bin/env bash
steam -nofriendsui -tenfoot
Open steam (from the desktop) and go into "settings > Steam Play" and enable "Enable steam play for all other titles" and select "Proton Experimental" then press "Ok"
On the bottom right of the Steam client press "Add Game > Add a non-steam game" then "browse" and select "all files" and browse to whatever windows app you want to use, in my case "Sega Model 3 UI.exe" and continue adding it.
then right click it in the library and select "properties" then "compatibility" and and tick the box saying "force the use of a specific [...] tool" and select Proton.

Open it, set it up and exit steam, from there on you can just access steam in big picture trough retropie and play your windows emulators.

Proton has been available for quite some time (2-3 years ?), is a Valve project combining based on open source projects like Wine or DXVK to run Windows games on Linux.

You can use Wine directly or install one of the Proton forks if Steam is not an option.

@mitu cool i didn't know this was already that old, apparently its even based on wine judging from the page you linked.

@Crush Proton is not new and has reached version 7. It is based on WINE and DXVK and some other stuff. You can find out what is compatible in Steam: https://www.protondb.com/

I use Proton on my desktop PC instead WINE. It can be used without Steam running too. But the Proton version needs to be downloaded from Steam UI first. I recommend Proton Experimental. Here is a script, you can try: Proton script Or you can try one of the forks, who added some more stuff and made it a bit better.
