  • DuckStation is a highly recommended emulator for PlayStation 1 games, and it works incredibly well on the Steam Deck.

  • After copying the games to the PSX folder, run MU Deck and go to tools. Select the Steam ROM Manager and generate the app list. This will add the games to your collections on the Steam OS system.
  • Once you’re satisfied with the added games, click the “Save App List” button. This will auto-generate everything into your collections on the Steam handheld mode.
