I guess this is more of a question regarding how the dock and its HDMI out works. If people make homebrew emulators like say Retroarch, would the devs need to figure out, understand, and implement the docking feature? Or does the Switch dock simply output the video to the TV once the device is docked, meaning no additional work is required? Reason I ask is because from my personal perspective, being able to play Retroarch on the go is always a major selling point. I have multiple devices that can already do that, but the only real draw back is that when I'm at home, I'd rather play on my TV or monitor, which means swapping saves between my PC and my portable all the time. This is where the Switch would be the perfect solution, if we were able to play emulators on our TV with the Pro Controller, and then carry on playing on the go later on.
