I have 3 questions to post here. 1. Can the R4i Gold be used on BOTH DSi and 3DS? Can they be used on both system to play... 2. Homebrew apps! I need to know if these cards are for just playing games or for using old homebrew apps like MoonShell and stuff. 3. Is it true that 3DS flash arts inject a bricking code to work after a certain amount of days and then it gets bricked? That scares me.
