If you're familiar with NES games at all, you know starting pretty early in it's history some of Nintendo's games had a battery inside that would save your progress, and they were pretty long-lived.I'd recently bought a copy of Tecmo Super Bowl, at noticed it wasn't saving any data at all. So I did some googling and it turns out there's quite a few folks on eBay that sell "kits" to fix it.They come with 1 teeny reverse torx (?) driver to take out the 3 screws that keep any NES game cartidge together, and CR2032 batteries that have the tabs that solder them to the cartidge board already attached.You simply have to take a soldering iron and heat up the solder for the old connectors, unbend their tabs going through the board, and gently pull them out.Then get your replacement battery and soldering wire ready. Heat up your iron, press the new battery's tabs though the board, bend them down, and solder them in. I don't do a lot of electrical work but I've used an iron before and it was pretty easy.You just have to be careful not to get your sodering area too hot and damage the board.This worked on my Tecmo Super Bowl cartridge first try! I should have another 25 years of gameplay and not have to worry about it not saving.My apologies for not showing pics of the old battery being taken off, but I did it by myself and don't really have a good tool to hold my work, do the work, and take pics at the same time.http://ift.tt/2tP6gSg via /r/DIY http://ift.tt/2twqbCV
