I'm trying to use a SNES controller on my original xbox. I understand how the snes controller works and I'm able to read its output. However, I can't find any info at all on the original xbox controller protocol. I know it's usb and I know someone somewhere must have done this before. I'd like to plug in my snes controller into a pic -> have the pic read it -> then have the pic send out an xbox signal to the xbox. Anyone have links to documentation or helpful info?

 

First hit on Google - http://euc.jp/periphs/xbox-controller.ja.html

 

thanks for the link. I'm still at a loss as for what to do with that information though. Does the xbox constantly poll the controller? I need to read more about how usb communication works. Any ideas how to implement this?

 

Here is a link to the source - http://www.usb.org/home

 

oh man, that seems so cold. the USB specification sheets are deep as hell and dry to boot.

I would personally suggest a direct 32 pin button to button mix up, saving time and, well, time. Figuring out usb, much less a console's usb is not the easiest. (I don't know if it's some proprietary data standard or not, but knowing that it's microsoft, if it were a standard ole HID i would be amazed)

They actually sell snes to USB converterers in different places. I know it's against the spirit of these forums to suggest a commercial device to someone, but hell, i'm way too lazy* to work that one out on a software level.
