Im having issues where some games will lose all saved data stored on the cart. These games are legit games and have had mods or illegal devices used on them or the system. Someguy1212 - 6 years ago

Most likely, the battery in the cart is dead. You'll need to get a 3.8mm bit to open the cartridge and a lithium battery to replace the dead one if you want the game to be able to hold your saves any longer. This is a very common problem with a lot of cartridge based games now and if you want to keep playing them this way it's just something you're going to have to do.
There's a faq here on Gamefaqs detailing exactly how you go about replacing the battery. It's not an overly difficult task.
