true but it will get harder when armadillo is used with the 'nanomites' and 'code splitting' options turned on.
armadillo is a tool often used for trial/evaluation versions of applications.
only JoWood used Armadillo v3.xx in the german Gothic 2 retail version to wrap the game´s exe.
if you want to know how to defeat armadillo, try googling for 'Armardillo Tutorial' or check some reverse engineering forums.
