Hello Guys, i've been using Mocha for now, and have also installed some titles already.
Can I still install CBHC?
Also someone's got a good tutorial IF?

You know I'm just gonna point you to my guide again.
Yes you can but CBHC requires HaxChi. Once you have HaxChi you don't need mocha anymore

And I'm going to point to my redNAND-free guide and wiiubru.com/guide
Mocha CFW isn't permament, it's just an .elf which is ran and kept in memory. You can safely install CBHC.

If you mean in like: fully explained what it does and blah blah, then kinda.
Current Up-to-date CFWs: Mocha CFW, Haxchi CFW, CBHC CFW.
Outdated methods: FW.img [iosuhax], redNAND

@QuarkTheAwesome -sama Help explain.
Well, I myself all I know that it was built to correspond with iosuhax and ARM processor. That's all I know.
Quark might know more since he's swimming in information.

Gotcha.
To understand what goes into a fw.img, I have to talk quickly about how the Wii U does things normally. On your average boot, the Wii U (specifically boot1, so keep in mind that this is mostly educated speculation) looks around SLC for a file named "fw.img" and loads it up. This file is an encrypted and signed version of the code that runs on the ARM/IOSU. Once boot1 has verified and decrypted it, it kicks off the IOSU and it handles loading the rest of the OS. The point to take away here is that all the IOSU-side code (kernel, modules, drivers, userspace stuff) is included in this fw.img.
("Probably how it works" alert!)
Now we get to talk CFW. Our old friend CFW Booter exploits the IOSU once it's already running and starts patching around the code in there. It removes signature checks and does a few other small things before commanding the IOSU to reboot the OS. At some point while it's rebooting, IOS-MCP (not boot1 in this case) goes to load fw.img from the SLC. However, CFW Booter has already patched it to read from the SD instead. Combined with the signature patches from before, MCP sees nothing wrong and loads up our customized fw.img. Ta-da, we now have a CFW running!
@QuarkTheAwesome Alright, thanks for the quick explanation. 
Do you know if there's a documentation somewhere or are those things generally "undocumentated".

Yes you can if you have a normally bought DS game with Haxchi installed on it.
