Sky3ds only plays online if you rip a bit of data exclusive to each game cartridge and patch a rom file with it. R4i ds-mode flashcarts work with the latest homebrew. No offense, but you're an idiot for being scared. Nothing bad will happen.I am very confused. So does Sky3ds+ play online or not? And do R4i work with the newest firmware? As I said I am not comfortable enough to homebrew anything. And getting a new 3ds for the same price I bought it for can be a challenge since it was VERY cheap.
