My example is blowing in old cartridges.
It is supposed to not be helpful, and in fact is definitely harmful.
But it always seems to work.
For example, I tried to put the game in several times, and it didn't work any time I tried.
Fed up, I did the blowing trick and the game started up immediately.
Hydrogen peroxide on any of my wounds. I kinda just like the fizzing.
Hoping for a good halo game.
