The same way you would reload an actual game. Go back to the system menu, go to the Loader, pick a new game.
Jeez, do you need instructions on how to turn the console on?
Yeah, you'll be able to run WiiWare/VC stuff off of a hard drive or USB stick.
I've installed rev14. I can confirm that the reset glitch has been fixed and that games that weren't working on 13b, such as Ghostbusters, works fine on 14.
People want are tired of the bugs on rev13 and they also want NAND emulation. Plus this was supposed to be out a week ago.
Still, that's no reason to annoy the guy or crash his website.
