Here's what i sent Oakwell It costs anywhere between £30 to £80 depending on chip, try to go for the Wiikey as it's upgradable by DVD it also depends on the processor that u've got inside the Wii, if u search the net u should be able to find places where u can put in the serial no and it'll tell u the chipset. As for the games as long as u stick to PAL u should be ok, apparently if u play NTSC games it can brick the Wii if u do the upgrade from the game. Nintendo are quite keen with their own games eg Super Mario series with the game being able to detect the chip. I had an older one in mine and it got to the stage when i couldn't play the newer games and the chip wasn't upgradable so i had the Wiikey fitted. I know i said call at Icon but i ended up searching the web cause when i called the guy at the shop didn't use the Wiikey but that was a while ago, he may do them now. Hope all this helps and i think i've covered most things for u, touch wood all the games i've done for the little un have worked fine. If u've any more questions i'll try and answer em.
