I just had a curious thought centering about how a game in such a screen size would be like in that custom-made viewport size, that doesn't deprive of crisp pixel perfect quality as other gaming systems have that kind of crisp quality.
I'm not just limiting it to one screen alone, too. I also mean dual screens, too.
The thoughts I were thinking of were past key 2D games that could do with the changed screen size to that, being able to see more from all sides with better reaction time in situations. Few among them were Sonic Rush, Sonic Adventure, Sonic Colors DS, Go! Go! Kokopolo, Mutant Mudds, Cyber Shadow, or any of Oscar's DSi games(of which haven't been done their longplays yet, so I've thought)
If anyone's got ideas on such games in that size, feel free to make mockup images on it, and base it on your imaginations. Just make an blank slate image with that size, and let your ideas flow.
I know no gaming system doesn't have support for that size, not even a handheld, nor any existing game engine, framework, or otherwise yet, but if one could be made with that and have such existing engines and frameworks updated to support that, well, it'd be neat to see.
Don't know where you'd place them for others to see, but, the floor's open to suggestions.
