Keyboard isn't working in game.

[Rhitter000]

I was trying to play Sonic Heroes for the gamecube. I went to the controller settings to check if the keys were right and to change some. They were responding so I thought everything was alright. When I launched the game and it asked to press Start, which I had assigned to left-alt, the game was not responding to the keyboard inputs. I closed it and checked the controller definitions again, and just like in the beginning, the keys were responding to my inputs and could even change them, but the game kept unresponsive. I don't know why the game doesn't answer.
Could anyone help me with this one?

Do other games work? Have you tried the latest beta build?
