You probably mean Europress' International Rally Championship which was
released last fall. You could check out the official IRC websites
http://www.europress.com.au/irc/default.htm
http://www.europress.co.uk/rally/rallyhome.html
but I doubt if you'll find any patches for the demo. They did release a
Direct3D version of the demo and several patches for the game itself, but
I'm pretty sure you'll have to buy the full version to get any liberties
regarding the controller options.
It is a rather enjoyable game, I admit. At least with 3D acceleration and
a wheel. After hours of precision racing and fine tuning with F1RS it's
primarily refreshing and relaxing to lead a rally car through night or
snow, where sliding through corners is more of a rule than an exception.
