Engineering user modifies a Steam Deck to add the Switch's Joycon rails into it
Reddit user, mrblackm123, is currently the owner of a Steam Deck, but started experience some issues on the controller side of the device. Due to the lack of replacement parts to fully repair the Steam Deck, the user opted to instead do something rather ingenious... to install a couple of Joycon rails (and Joycons) right into the Deck console, or rather, the stripped down tablet/motherboard of it without the controller sections.
The video showcases the Deck's tablet alone with the side rails installed, and then followed by the user promptly attaching the Joycons to the side of the Deck's table to start playing a variety of games with them, from using the Joycons to play Cyberpunk 2077, to Link's Awakening playing through emulation on the device.
The post itself is available on Reddit, under /r/Steam Deck. However, it seems the moderators of the subreddit might have mistaken the device for a Switch console of sorts, since they removed the post of the user. Hopefully the post itself can be reinstated once the mods realize their mistake.
