How do you know if a non-Steam game will work on Steam Deck?
Adding non-Steam games to your Steam Deck is pretty similar to running games on your PC that are not from Steam. This is because the Steam Deck essentially works as a hybrid between a PC and a gaming console. As long as you know how to download and install a game normally, you'll only have a few extra steps. So, there's no verification process. If you can install the game on your PC, you can also do it with Steam Deck.
