USB Adaptors plugged in, mame is choosing the wrong ones can i fix this?

[mrclean]

I have about 4-5 alternative USB game adaptors currently plugged in to my computer.. including 2 ultimarc U360's. Mame is using my N64 Adaptoid as a controller, as well as an NES controller for player 2.. I'd like to have mame use my new U360 sticks instead. How can i do this?

As long as MAME recognizes all the controllers, you can set whichever controller to be player 2 or 3 or 1 or combinations of all of them including the keyboard and mouse. Just go into the configuration options, go to the button you want to set, press enter, then press the button of the controller you want to use to control that button. You can then press enter again and set an additional controller to use that button. You can repeat this for all controllers.
