Ah, the good ol times...
I never played Gradius, only Parodius, but that was really cool. Was that the "Konami code" he was trying to use? whatever so could you make him play Casltevania 3 next time? wait wait Mario Bros 3? NO forget it Snake Rattle n Roll (thats the name in Germany, two snakes eating little balls too grow longer)? Or even better Metroid?
Ah now I know: Battle for Olymp!!!
So yeah good movie :)
