I've followed the awesome instructions here and have been playing games from my USB HD for a couple weeks now. I've also setup some emulators and love my Wii.

But I still haven't seen an up to date, very simple explanation of how to deal with Wii Ware games, specifically playing them. How can I just get them to show up on my SD card menu like the stuff I bought from the Wii Store? Do I have no option but to use a loader like Wii Flow? It can load the WADs but my favorite loader is actually USB Loader GX. I don't really understand what NAND emulation is either.
