So, I've got quite a few questions about hacking my Wii U with all the latest stuff. Feel free to send links to posts or answer them yourself. THANK YOU 1. My Wii U is on 5.3.2U. Should I upgrade to 5.5.1? 2. What's RedNAND and IOSUHAX? 3. What's the best CFW at the moment? 4. Do I need to have NDS VC game purchased? 5. What is this fw.img? What do I need it for?
