Remember how video game cartridges suddenly started working when you blew on them? Oh, you don't? Get the hell off this page then, you filthy Gen Z'er.
I've got you covered. Blow side to side four times, up and down twice with cold breath, and then hold the cartridge down for precisely two seconds while holding the power and reset buttons for 1.5 seconds after having pushed each of them three times for six seconds...that should do it.
