Hi,
I don't have this game so I never tried to install it (you tried with LiveInstall I suppose).
But, we can see in the Wine application database that the full version of the game has a "garbage" mark (see
HERE), because of the safedisc copy-protection. So you'll can't play to MotorCross Madness 2 as long as its CD protection will not be support by Wine.
Sorry, we can't do anything for the moment.
But don't loose hope ! Firstly, because this test was made more than one year ago and secondly, because the Demo version of MotorCross Madness 2 (from Mircosoft website) seems to works in latest test (see Wine appdb
HERE).
To summarize, I can't help you (I don't have the game) but everything isn't lost.
You should try the demo version to verify the last test results.
Bye
