The developer of Rig'n'Roll has announced that the cheats have been removed from the game, and the ones on the internet will not work for any copy of Rig'n'Roll released in 2010. The following was taken from an interview With Igor Belago on the offical RigíníRoll site:
Q: Will cheats be put in international version of game on? A: No, there will be no cheats available in the game. More over, we strongly discommend using any hacking software, since there were already game malfunctions detected during the attempts to make more money.
