Anti Piracy

The game checks whether a copy is legitimate or not at runtime,
checking its registration code through a web server.
Should an illegal code be detected, the game will run normally
for four levels, then lock up on a "LICENSE AGREEMENT VIOLATION !" screen.
The only option is to press any key and quit the game,
which will then revert the game to an unregistered state.
