since AUS wii is PAL, so some of these NSTC-J games will never in AUS game shop, the only way to play it will be install a wiikey, that is why for aussie only (just show what have we miss out)
maybe we will see a Freeload for wii soon
why there are NSTC and PAL shit, i wish all the consoles are like NDS and PS3 (region free)
