Hiya ppls. Good to see there's interest in this project still.
Ichibo: If the PIU pad acts as a USB keyboard then its theoretically possible. If its working as a USB joystick device then it probably won't without some sort of driver. I don't have any idea on what would be involved for getting such devices working on the Xbox.
With the current version we're working on, you don't need a USB keyboard to map the controllers anymore.
At the moment, our main focus is keeping up with the development and making sure any changes are compatible with the Xbox version. Right now, the current version isn't supporting characters or other themes. We'll be looking at fixing this up, adding vid support and maybe looking into implementing virtual memory.
Once a stable version is made that is actually worth releasing we'll look into doing it, though I have no idea have one distributes things in the "usual places". I know Xport is looking at porting StepMania once the stable release is out, and with his superior coding skills and previous experience with distribution, it will probably be from him that you will end up getting it
Oh and just so you know, we now know that it works with Evox M7
and M8. Wow!
That's all for now. More as it happens.
