Blowing Game Cartridges
Back before the PlayStation came out, we were stuck with game consoles that ran games off of cartridges. There was the NES, the SNES, and Gameboy. Whenever the console couldn’t properly load the games (you could tell by there being weird lines on your TV screen), there was only one solution: extract the cartridge and blow into the connector thingy. And it worked nearly 100% of the time.
Here’s a pretty funny story that ends up costing our parents around $20 back in the day. When we visited FuncoLand (currently known as GameStop), the salesman there totally duped us by saying blowing the cartridge could cause irreparable damage to it (might’ve been true because, y’know, spit and all). So, we bought a bottle of alcohol and a special cartridge-cleaning tool that worked just as well as blowing.
