Seems to run on Linux under Proton

[TippingGoat]

I have recently obtained a Linux PC (Ubuntu), I got Steam installed and was able to run Super Slam Dunk Touchdown and play with a wired game controller, but i had to force the game to use Proton before I could install it. If you right click the game from your Library, there's a Properties option, pick that and go to Compatibility. From there you may be able to choose Proton, and if so, it may work. Kind of a modern miracle, but it works on Steam Deck so I assume it's a similar thing.

If you have Linux and want to try it out, please reply with your experience with it.
