With RetroN 5 and similar systems out, Cartridge EPROM batteries are getting to be less necessary all the time, but in cases were you do still need them (i.e. N64 Games and Controller Packs) they might have just got WAY cheaper and easier to replace. For those mailing carts off to have this service done, this won't be helpful, but for those who are Do-It-Yourselfers who every 7-years or so hunt down 2032 batteries with Solder Tabs, this becomes like a gaming "Class Reunion". You take all your Carts apart, realize half of them don't need batteries, then you go to the ones that do and realize just how much you forgot about soldering since the last time. After a few hours, the problem is solved and you promptly forget what a hassle this is. Well, to make matters worse, batteries with said solder tabs are harder to get in new condition, and the configuration of the tabs isn't always doing you any favors when it's time to put them in.
Well, here is a new product that might just have made this WAY easier. BUTTON BATTERY SOCKETS - that can be permanently soldered to the Cart-Boards and then normal 2032 Button Cells like you find in PCs and Dreamcast VMUs can be slipped in as needed! See this eBay auction for an example: (
https://www.ebay.com/itm/5XCR2032-CR202 ... 3789176897 ). Then all you really need is just a Nintendo socket tip to keep all your games ready to work indefinitely.
This is reasonably easy to do, but for anyone who might want to have it done, am happy to quote a price based on how many games/controller-packs and shipping.
