Loadiine was the first and desperate attempt at playing hacked games on Wii U, and for the most part it ran them poorly and some not at all. Then the Brazillian method came and it blew it out of the water. It doesn't matter if you don't have a DS game (which is kinda ridiculous though it's only like $7 and would save you from using the browser exploit ever again) even through the web browser exploit though you can use the Brazillian method you just need an external hard drive with y cable and install your games through WupInstallerGX2 from the sd card to the hard drive.
Loadiine does not load homebrew apps it only loads Wii U and VC games, but again poorly.
