Something like Rockbox would be neat. I know it's for MP3 players, but it pretty much offers what you're talking about. This is actually the first piece of homebrew I ever used in my life. Used to run it on an iPod Classic in middle school. I'm getting nostalgic at the prospect of running it on a 3DS, heh.I feel like the entire 3DS "home screen menu" could just be replaced with a no-frills text menu, maybe with touch controls on the bottom screen.

Also, it apparently can run on ARM9 and ARM11 devices, so that's promising.
