Modifying the Robocode Game.
Perhaps it is only declared as AdvancedRobot in RobotPeer, but the instance is a FreezeRobot (and, more specifically, your robot class)? If you were seeing the instantiated type, it would show as your robot class. No matter the declared type, in Java you can do "instanceof" to check whether the actual instantiated object is a certain class (like FreezeRobot, or DrussGT), so maybe give that a shot and see if it works.
But yeah, as these guys said, the robocode-developers group and project forums are better places to get input from people who actually work on Robocode. They don't compulsively check the wiki as often as us Robocode addicted bot authors. ;)
