Whew! I was blown away with the large amount of homebrew applications and games for the Nintendo DS when I found this website. For those interest, you have to have a NDS/NDSL (duh!?!), a decent flashcart (I recommend R4 or M3DS Real), and a DLDI patcher (but rarely need it since new kernels auto DLDI homebrew nowadays, but just in case...). Enjoy!
