Since I wasnt sure what I was doing....
D4)Install wads (careful with that, ok? youare not priiloader safe. Definately do not uninstall ANY IOS LOWER THAN 200!!! You will brick! I repeat for the Butt-heads: Do not uninstall ioses with a number lower than 200!!!)
To install wads, select wadmanager, and choose ios249 and SD card on the options (should be default).
-If you want Neogamma as a channel , install Neogammar8.wad
-If you want USB loader GX as a channel, install USBLoaderGXr850.wad (this will install the full channel, but you can install the forwarder instead, USB Loader GX-UNEO_Forwarder.wad, which can be directly updated by placing updated version in the SD card, yet you will need the SD card constantly inside the Wii slot to launch it. Install whichever sounds more useful to you)
Note that your HDD needs to be formatted as WBFS with WBFS Manager.
The following are really optional and not needed to play backups. Also mind that incorrect use of them might brick you!! so use with caution!!
