Game Boy Save Manager lets you back up and restore GB save files using a Link Cable

Game Boy Save Manager is a project by Robin Grönberg (Gronis) which lets you back up and restore Game Boy save files using a Link Cable and two original Game Boys. Gronis’s reasons for making it were down to convenience and cost: There are certain hardware products you can buy to backup and restore SAVE files from and to your Gameboy cartridges. However, many of us probably have all the necessary hardware at home to do this already, so buying another piece of hardware for 35-50$ just to do this seems unecessary(sp?). All you need are 2 Game Boys that have a Link Cable slot, the game you want to save/restore a save from, a GBC link cable (and adapter if you’re using a DMG), and a flash cart. The save manager comes in the form of a .gb ROM which you save to your flash cart (full information is on the repo)
