its a hack that lets you play import games, takes off region lock ect. Acts like an emulator can play a bunch of games from NES-gamecube. Im not sure but i they might be cable to emulate some ps1/sega saturn games too. there are apps for it like an internet app that has flash player on it
also using an SD card you can use it as a movie and music player
so lets say you torrent a bunch of movies and put them on the card you can watch them using homebrew
Right now homebrew only works in "wii" mode so technicaly the Wii U is still not hacked. Also once you homebrew you lose warranty and can brick the console if nintendo finds a way to brick it with an update
UPDATE:
right now im catching up on Wii games. wii u upgrades resolution output to 1080p. regular wii only has 480p( i never purchased wii) playing xenoblade chronicles right now (best game I played in years), got zeldy sky sword, super smash bro and last story on backlog
played demo for nba2k13(SUCKS!) and zombie wii u. zombie was fun and i can see how it could be scary playing alone at night but not at the top of my list. maybe in the future ill get it but too many games right now
Rayman legends demo is my shyt! 100x better than mario and the graphics are unbelieveable. I am definately getting this. I never really been a platform guy but supermario wii u and now rayman getting me back into it
hold on i know a lot of you are upset right now so take a breath
ready?
other games im looking foward too
