WAD Manager v1.3
Link-Get an SD card and place this app in /apps and then make a folder on the root called /wads and place all wads in here(Next part).
USB ISO Loader [I recommend the Brisma mod, but it crashes a lot for me]
Link-put the wad in /wads and put the app folder in /apps
Backup Launcher
Link-Download the wad and put it in /wads and download the app and put it in /apps
The run WAD Manager through the Homebrew Channel and choose SD (for the source) and then install both the Backup Launcher wad and USB ISO Loader wad.
There, now you have a channel for each of them and you can also run them through HBC.
You MIGHT need cIOS for them, though. I don't remember... if you do, then just google it and get the latest.
