Most people probally know of DSOrganize.
If not it's a slimed down PDA for your DS
I don't have a Flashcart or anything that I could put the download onto, and then put into my DS.
I was thinking of an R4DS because its most popular, but CycloDS is cheaper, and then again thers the M3
I don't know which to get, I'm mostly just want something that can run the organizor, play movies, and play mp3's
