so.. yeah these are like the gecko cheats for wii.. but not ._. First off you need to downgrade your browser (for emunand users) i've downgraded my browser on 10.7 rxtools emunand. you can find a tutorial here. then head to this website. choose a game you wish to "cheat" in my case it would be Fire Emblem Fates special edition USA. boot your game and choose a save (again i'm using FE:F USA as an example) then once the castle loads press the home button (once any game boots press the home button) press L+R then click on the qr code button then scan the AR code cheat the cheat will then tell you to open the browser select yes the cheat then will inject and the browser will crash open your game and check if the cheats worked. IF YOU NEED ANY MORE HELP JUST TELL ME!!! although this is pretty simple. i might upload pictures if told to do so. please notify me if this is confusing at all and i will edit it.
