I don't think the 3DS is even close to be fully documented. Homebrew is still very recent in terms of where we are with regards to the Wii and DS. And that's why it's so exciting: terra incognita. We won't know the requirements until most of the hardware gets emulated and the accuracy fairly matures.
I'm working on my GB/GBC emulator at the moment (incubating code for a GBA emulator) but other than that, I can dedicate a large amount of coding time to another project. I used to work on Gekko (another GC emulator) but things didn't go to well. I'd really like to get into a project like this early on and explore the hardware from the ground up. Might as well use my tax return to get another 3DS for development (at any rate, my sister and I have to share one anyway... so I need another one regardless).
