funny! Yes, it's only 9999 combinations, and if it doesn't lock you out and you can get one code in a second or so, it'll be 3 hours. And like they teach in math class, the expected value is about half of that, so you might be done in about a couple of hours.
reminds me of the Ferris Bueller Day Off scene with the kid spinning the wheels in reverse to count down the odometer.. It didn't end too well though
but call nintendo, and as long you can convince them you're not a 8 year old they should have a master key to help you.
Actually there are 10000 combinations cuz u gotta count 0000
