Is the Wii Points generator legal?
No. It is illegal. Wii points are to be used only from Wii points cards. Any other way of getting them (as by the Wii points generator) is not legal.
OK, the easiest way is to buy a wii points gift card at a local gamestop, radio shack, or even CVS. The more wii points, the better. Register it onto your wii and there you go! You can also buy wii points ON your wii buy going to the wii store on your wii. You can add in your credit card info and buy as many wii points as you want really!
