Well, today my package arrived and it contained two Playstation2 games (DanceStage Fusion and DanceStage Max) and my Deluxe DDR Ignition Dance Pad (with a USB connector!)

Now I can also play games like pydance and Stepmania on my own computer. Apparently Feisty automagically recognizes the pad:

input: USB Gamepad as /class/input/input11

input: USB HID v1.10 Joystick [USB Gamepad ] on usb-0000:00:02.0-2

Got to go and lose some pounds (playing Fusion on my PS2) and have some fun.
