I'm just curious about something here. Somebody recently posted a list of nintendo's top selling games for the past month. Brain Age was #1 on that list. Obviously this game is #1 because it's purchased specifically for Coldboot Haxchi. My question is this... If Nintendo knows that this DS game, as well as some other DS games, are used for hacking the Wii U, why hasn't Nintendo updated these games so that the exploit is patched/blocked? Is it not possible for Nintendo to "fix" these games, or is Nintendo just being lax on the issue here?
