i heared that wii u can be modded to play homebrew games so my question is:are homebrew games the pirated games that we can download from the internet to burn on a cd or something(iso or cso i think) so can it play those "pirated games" or copy them on an sd card like the r4 for the ds because i won t buy a wii u except if i can play cheap games because the original ones are really expensive
