Backing up your saves is important in case you want to save them forever, or if you want to swap out the battery in your cartridge. Most of those batteries were manufactured in the early 90's so their lifespans are quickly coming to an end. I was able to back up mine at the end of 2019. I'm not sure how much longer they would've lasted but I feel relieved to have my childhood saves intact. You can extract the save files from your cartridges.
You can inject save files from emulators (NOT save-states) onto your cartridges. You can dump your Super Nintendo / Super Famicom or Sega Genesis / Mega Drive cartridges into ROMs to back them up legally. 2 Super Nintendo controller ports and 2 Genesis controller ports built-in and you can play directly from the cartridge using an emulator using these controller ports. Expandable to work with other systems like the Nintendo 64 and Game Boy using adapters (included in this bundle).Important: You need to change the voltage setting on the Retrode 2 base unit depending on which type of game you are playing. With the N64 adapter, voltage should be set to 3.3v. And for the Gameboy adapter, you should keep it at 5v for Gameboy Classic and Gameboy Color games, but you need to change it to 3.3v for Gameboy Advance games. Failure to use the correct voltage could possibly cause damage to the unit. This item is in the category "Video Games & Consoles\Video Game Accessories\Cables & Adapters".
