Man, I can't wait until my Pop'n Music controller comes. Finally figured out how to play 9-key Pop'n Music - by plugging in my two Beatmania DJ Station Pros and doing a bunch of key config alterations. What we have now is 10 keys total (clustered together in groups of five, about a foot apart), with the middle button of the 9 used in PnM duplicated on each controller. It kinda makes sense when you see it, and it lets me get a decent idea for the game, but man, it's still pretty funky.

And of course the guy that I'm buying the controller from isn't shipping it out for a few days still. So much for maybe having it for this weekend. Blah.
