Hello guys so, As some of you may know I've got my 3ds hard modded, downgraded and with cfw and homebrew installed, and now I've go a few questions. I was wondering if there's any way to use codes like the old Gameshark/action replay codes that were used on the DS? I heard that Gateway works for this, but I need the flashcart to use it, right? Or can I run just the software? (can you guys point me to a guide?) Is there any other way to cheat? Keep in mind that I don't use official game cartridges, I just install the CIAs.
