So...I'm gonna buy a second hand Wii U...(For $215,It's El Salvador,the price it's actually decent) and my firend says it's already hacked...but he says you need to get into a website in order to load the games you have installed and that the hack modifies the mii maker or something like that....and i'm wondering...what hack is it? can i change it to another one that I can instal games directly or at least make forwarders? will i be able to play Gamecube and wii backups with that hack?
