Forgive me if this sounds stupid, but I had a thought come to me last night about this.
So, you know how there's homebrew programs for the PSP and DS that allow you to use your system as a PC controller? I was wondering, would there be any possible way to, through a combination of a setting on this emulator and a corresponding homebrew program on a 3DS, that would allow you to use the 3DS as a PC controller, control the game running on the emulator, and use the touch screen on the system to control the touch functions on the emulator?
The reason that I think something like this would be a neat idea is because of the HD upscaling the emulator can do(could, now that I see the post above, but I figure that will be brought back at some point). If you only displayed one screen, and made it full-screen, you could use the 3DS itself for the bottom screen, and play your games in full HD.
No, this isn't a feature request or anything like that. I figure something like this would be rather complex and unlikely to actually be done. I was just curious if this would be possible, or if it's just a stupid idea that wouldn't work in the first place.
