not an officially licensed product of Nintendo, but spending 10-15 bucks
on one of the NES "cleaning kits" was, is, and always will be a complete
waste of your money. All you need is a bottle of Rubbing Alcohol and
Q-Tips. Dip the Q-Tips in the alcohol and rub them on the exposed chip
portion of any game cartridge that you can't get to work. The game will
then work, guaranteed. No more futile process of blowing on the games in a
desperate attempt to get them to load. Use these two simple items and your
game loading problems will be a thing of the past.
But, if I
may make one suggestion... please don't use the same Q-Tips in your ears
that you plan on using for your games. Definitely not a good idea.
