So I'm thinking of buying a Wii U (preowned for cheap) but anyways are there any homebrew for Wii U mode (so no vWii I already know of that)? And if so is it full kernel access or only userland? I have previous homebrew experience with 3DS and Wii, but I'm brand new to wii u. Could someone fill me in about safest and latest firmwares, if CFWs are possible, etc. Thanks.
