I just bought a brand new 3ds. And while I've been waiting for the good games to come out I keep thinking about how I hacked both my PSP 1000 and PSP 3000 using the memory stick for it to install all my CFWs and games to run off of. So my question is why do you have to buy a special cartridge like the R4 to hack the 3ds? Why can't I just use my memory card for it to do everything? It just doesn't make sense to me that you have to use 2 seperate components to hack a 3DS to run homebrew etc... Can somebody please enlighten me?
