If you have a large collection of physical retro games, then there’s a good chance you’ve experienced the issue of internal batteries failing over time.
Systems such as the NES, SNES, N64 Mega Drive/Genesis and the entire Game Boy line used internal batteries to maintain save data, and once those batteries run out, you can say goodbye to your precious save data.
Some people are pretty good at opening carts and changing dead batteries, but a more elegant solution has just come out in Japan. “Basket Reader” from Save the Hero Project is an open source device that allows you to dump ROM and save data from your existing cartridges and even download save data from emulators to your carts.
It supports SNES, N64, Mega Drive/Genesis, Game Boy, Game Boy Color and Game Boy Advance and is a completely standalone solution where you can take save data files and transfer them to your PC or emulator device. if you so desire, you don’t really need any other hardware to use Cart Reader’s most basic features: archiving and restoring saved data.
The device was funded by Kickstarter worth 3,378,620 yen (with a target of 1,500,000 yen), with each unit costing 10,800 yen (roughly £70/$93/€82), and the team behind it says global sales will open soon.
Here is a fantastic overview of the device thanks to Macho Nacho Productions:
