Cheat codes for anyone who wants them, translated to the bumpers since there are no black/white buttons:
NOTE: You have to highlight the stat you want to use the code for. After you type in the code, immediately press A. While holding A, back out of the stats menu and the effect will still be active. There are two caveats. First, if you navigate to any other item on your stats page, or any other page in your B menus, you will have to reapply the code. You also cannot apply any of these codes without having already lost any health/magicka/stamina.
