The Nintendo DS was a wildly successful console, but emulating its unique dual screen design on modern handhelds is a challenge. You can try to squeeze both screens onto a single touchscreen, attempt to completely recreate the DS’ unique hardware, or do what Retroid is doing and release a temporary clamp-on, secondary screen that’s compatible with its handhelds and other third-party devices.

The Retroid Dual Screen Add-on is currently available through the company’s online store in black, purple (inspired by the GameCube), and translucent white color options for $69, but are currently sold out. That includes a version designed for Retroid’s own Pocket handhelds including the RP Mini, RP Mini V2, RP4 Pro, and RP5, and the version for third-party handhelds. As long as a device isn’t taller than 115mm and supports DisplayPort over USB-C it should be compatible, but Retroid specifically points out the Steam Deck is not.

Featuring a 5.5-inch AMOLED screen with a resolution of 1920 x 1080 pixels and dedicated brightness buttons on the side, the Dual Screen Add-on attaches to devices with an expanding clamp and can be positioned at three different angles using a “click-stop hinge.” However, the second screen can’t be folded flat against the handheld it’s attached to like with the DS.

The add-on features touchscreen functionality, which is supported through the DisplayPort protocol. If your handheld of choice is lacking touch capabilities, hanging the add-on off the bottom will let you play DS games that heavily relied on lower touchscreen interactions. But since Retroid’s Dual Screen Add-on is at its core just an external display for a handheld, what games you can play and how the screen will be utilized is left to the device’s operating system or the emulator you’re using.

The add-on weighs around 130 grams, thanks in part to it skipping a built-in battery. It’s powered directly by the device it’s connected to, but it does have its own USB-C port with pass-through charging capabilities so you can keep both the display and your handheld running without killing its battery.
