can you use a usb xbox 360 controller to play gameboy roms on a computer?

I'm not exactly sure as I don't own an Xbox PC controller, but if you plug it into your computer, it functions as a regular usb controller, correct? I don't know what emulator you are using (the more info, the better), but there should be a menu somewhere where you can customize controllers. There should be an option to use a joypad (aka usb controller) as an option, and you can set the buttons from there. Again, that is what works for me with my Logitech usb gamepad. If the xbox controller doesn't work like that, you might want to pick up a usb gamepad at your local electronics store. I know logitech makes an bunch of different ones and they're pretty affordable. Hope that helps in someway.

Ah i see. I think so, since it is made to connect it with a PC or a laptop, but maybe this will be only suitable with some games but not all. Try to connect the device to your PC. and then if the device requires installer try to search on download.com well if the controller doesn't requires an installer. Well that's good. Try to play a game for you to know.
