Of course. But the tcpgecko.elf is bugged with Twilight Princess. If you play the game and connect to it with JGeck U, your Wii U will crash after doing different things. If you pause and unpause your game, the Wii U might crash. If you leave the current area, the Wii U might crash. So.. WW HD is currently the best game to hack, since it does not crash there.
