My uncle swore by using a hairdryer on old game cartridges, and he was totally right

I was trying to get my old Sega Genesis copy of Sonic 2 to work for like an hour, cleaning the pins with rubbing alcohol and everything. My uncle, who fixed arcade machines back in the day, told me to just take a regular hairdryer, set it on low heat, and blow it into the cartridge slot for about 30 seconds to drive out any moisture. I thought it sounded like a dumb hack that would just melt something. But after it cooled down, I popped the game in and it booted right up on the first try. It's been working fine for three weeks now. He said the old boards can get a little damp inside over the years and the heat just dries them out gently. Has anyone else had luck with this method, or did I just get lucky with my specific console?

Your uncle fixing arcade machines makes him a legit source, that's awesome. I had the same "this will melt it" fear with an old NES cartridge that just showed a blinking screen. I used a hair dryer on low for maybe 20 seconds over the chip area, let it sit, and it worked like a charm. It's a solid trick for that old hidden moisture.

That hair dryer trick is a great way to bake in the problem for good. You might get a quick fix, but the heat can weaken the solder joints on the board over time. It's just moving the moisture around, not actually getting it out. For a real fix, you need to open the cartridge and clean the contacts with the right stuff. A temporary blink fix isn't worth the risk of cooking the board later.
