For you who are having problems with moving the datafile to the right location, could you tell what error message are you getting? Without telling it nobody can help you. And remember to check that your pak0.pak -file is where I adviced to place it because if it's in any other place the command for moving it won't work.

No, don't do it as root. Please stop trying to solve X Term related problems with running everything as root. Running things as root may seriously messu up your phone beacuse running things as root makes some files to belong to root user and after that they can't be used as normal user anymore.

You can set your own controls and check the default controls inside the game in Options>customize controls.
