This is an awesome guide, i have previously installed all of my VC/Wiiware wads onto my emulated nand for use with triiforce.
1. Preparing your Wiiware and VC .wads is the next step
2. Gather all the .wads into one place
3. Inside the "wip isof" folder make another folder called "wads"
4. Copy all the Wiiware and VC there
5. Now in ShowMiiWad do the following to add the .wads to queue
6. Make sure you are in View ----> ShowMiiWads
7. Click File ----> Open Folder ----> Find the "wads" folder in your "wip isof" folder
8. If you have .wad's there you should see this in ShowMiiWads GUI
