Let's say you bought a pair of cartridge-based games to go with your Nintendo 3DS, but you're embracing our all-digital future and want to replace them with downloadable copies. You won't have to toss all your game progress at the same time: a newly available 3DS firmware update includes a tool to move save files from a retail copy to its downloadable version. The transfer is strictly one-way, though, so there's no falling back for gaming Luddites. Nintendo offers a bonus if you're fully in step with the online world, though -- background downloads can now start just by closing the lid while the eShop is running. Both elements of the update are simple on the surface, but they could go a long way in helping us ditch a legacy of plastic game libraries.
