There is a free ad-supported version of xRC, if the ads annoy you can buy an ad-free version of xRC.
Does it work with a (PS2/360/PC/etc.) gamepad?
I have only tested xRC extensibly with an original XBox controller, however, xRC uses DirectX to retrieve gamepad
input, so I'm fairly confident that a good variety of gamepads are supported.
Yes! I really enjoy receiving ideas and feature requests and always strive to integrate them in a timely manner
(depending on the feature, of course), don't be shy! You can send them using the support page.
