I used Px HDD Loader v1.2a to copy Project Gotham Racingfrom the value series) to my xbox hdd.
It should disable every copy protection.

I can play it, but after some the game doesn't react if i push buttons, but the game itself continues.

It there anyone else with this problem?
And how can i solve it ?

I also found this problem on another forum:

Turn off IGR in Evox. should sort it out.
