I already have a gateway for my N3DS and then I have my always-up-to-date old 3DS where I play bought games. I saw that you can download homebrew to the latest firmware so I thought to myself "what the heck might as well do it before it gets patched". After downloading it and whatnot, I have no idea what I can do with it that I can't already do with my gateway? I mainly use my gateway to play hacked roms and that's basically it. Suggestions?
