Hey Andre, glad to hear the Asterock free play worked for you. Sounds
like cosmetic side effects but, hey, what did you expect for a 2 byte
change to the code? Shoot me an email if you would like me to dig a
little further into the source and do some additional clean up. I have
never seen the game and probably never will so you would need to do ALL
of the testing. ;-)
