I am a beginner myself and I have zero experience in porting so I don't know how helpful I can be. I do know C++ and OpenGL ES 1.0 and 2.0. I know a little about java, but I am willing to assist as much as I can.
Does the game yield a debug file, a log file or something simailar so that we can see where it's having problems? If you find one please post it.
