Just two (so far). Will borrow my friend's Wii version soon (Seeing the PS3 portal works with it). And I do want it as a portable so I'm getting the 3DS version. --- GT: Ayumi Spender ~~~~~~~~~~ PS0: 4597 9585 4793 Only talk to me when I order you to.
Take an object that sits about an inch over the main platform of the Portal of Power (referred to hereafter as "PoP") and place the figure right on top of it when the on-screen prompt asks for the figure.
I use a roll of electrical tape for all of my "defective" figures that cannot be read by simply placing them on the platform of the PoP.
It is somewhat annoying to remove the roll sometimes, but at least all of my figures work with no problems.
See if it works --- http://users.ign.com/collection/gymleader_panther - Over 2,000 titles served! ^_^
