Hacking A Lot of Wii U Hacking Questions

[Wellington2k]

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?

1. All new hacks only work on 5.5.1 so yes
2. IOSUHAX is a hack that allows all kind of stuff. redNAND can be thought of a wii u emunand
3. Mocha https://gbatemp.net/threads/mocha-cfw-the-sweet-chocolate-to-your-latte.452940/
4. I would recommend it as you can quickly boot homebrew and cfw with haxchi https://gbatemp.net/threads/haxchi-v2-0-a-persistent-wiiu-hack.451071/
5. fw.img isn't need with mocha
