Alright, so now I have a small wiki called "NDS Wiki" that is just starting but quickly growing. There is also a sister site called DSHAX, and because of the fast success the sites are generating I've decided on creating my own emulator for GBA. Only problem is have no idea how to start from scratch. Any open source emulators or engines? And yes I know i's gonna be hard, and take months, so please no comments about that. Thanks!
