Okay so hear me out, I'm not very sure how fast the Wii U can receive from a computer or other device, as I've never tested it out, but my wondering is that maybe we could keep our Wii U game files on a device "similar to how PS2 games were stored and sent to be loaded" with much bigger storage such as a personal server, Desktop or Laptop (for more portability). Since you obviously load homebrew from a personal server, maybe there is a way you can load games as such? Maybe an adaption of Loadiine that can display the games you have stored, and when you press which game you want, it will "stream" the game. Good idea? Yes. Possible? Maybe. I'll let you guys decide.
