mame and wahcade python error

[eternal_sage]

i followed this guide with a little help from here as well. everything seems fine, but when i start wahcade from terminal everything comes up as if it is fine but i get a window with this message. running this on ubuntu 11.10 64 bit if that matters, with the setup files that are found here. thanks in advance!

Looks like a problem with the joystick, it's either looking for one that's not there or it's configured wrong. Can you post your config file?
