I probably spent just as much time trying to get my system to work than I actually spent playing the games.
it's all about blowing in the cartridge. and in truly dire times, sometimes you had to blow in the system. then you had to get the cartridge in there just right and voila, it works.
i can see it now, you call the damn customer support line bitching about how your shit isn't working "well, sir, have you tried blowing in it?"
it was the only thing that worked.
