Well the wiikey is good,but it seems that the wiikey team is dead...Lets explain to yuo the situation:
One month ago,people discovered that the LEGIT Super Smash Bros Brawl (J) Disc is not working with wiikeys.Strange thing is the SSBB backup works.Wiikey team posted on wiinewz 1month ago saying they were working for a fix...But no news since that.The yaosm programmer said it was a fix that could be made in 5minutes,very simple...So wiikey users might never be able to play the legit SSBB.I have a wiikey and i was planning to buy the game,so i think it is very deciving.I would not recommend the wiikey for that.
