Sure, modern PC games aren’t designed to run off of a Nintendo DS-inspired monitor setup, but this Steam Deck mod adds a second screen anyways. Put simply, it consists of a 7-inch portable 1080p FHD monitor attached using a Rolling Square Edge Pro Tablet Kit.
The hinges that you see are are modular, which means they can be quickly and easily removed from both devices with a slight pull. To ensure everything stays powered, a mountable battery pack on the Steam Deck that clicks on provides extra charge, while these magnets are thin enough so it still clips on with the magnets adhered to the back.

Use Citra emulator or a DS emulator that allows 2 window mode. Once toggled on, make sure you go to desktop mode on the steam deck. In settings>display I set top (2nd) screen resolution to the default 1900×1080 and moved it into the top position. Make sure it is on extend, not mirror, or any other mode,” TyePower.
