Yeah, it looks like the photo I snagged from Wikipedia is that of the Puchi Carat controller. I've seen (but can't find right now) pictures of the Namco one and the design is exactly the same, but with the drab, beige color and Namco logo. I'd be happy with either one. I also just remembered that I have Arkanoid 2000, and I bet it would work with that.
I also just realized that I've got the NeGcon controller (2 of them, actually), and I bet I could use that for those games. Still, I'd love to have the actual special paddle controller.
By the way, anyone know the code/procedure to unlock the hidden Bomb Bee game on the Japanese Namco Museum vol. 2?
