Alright guys, yeah they have been in the uk for a while now. I personally have orderd a wiikey from the states just because it was available pre-order. I'm sure it wont be long before they are freely available here.
My brother got his done last week. It was the Wiinja chip that the guy installed in it. I have seen it playing back ups so can confirm that as far as that is concerned it`s 100%. the chip itself is a Pic chip, with 5 solder point ( really easy ). Oh and make sure you get the version 2 wiinja chip as this covers both drive version in the wii at present.
fitted wiinja2 last week and works fine but i havent tried an ntsc game to check. fitted myself and wasnt too tricky to do either,make sure you use as thin a siolder iron as possible though as it can be a bit finnicky
