Memory loss is most likely due to the battery in the cart dying or becoming loose. There is a way to to make the SNES able to play foreign and pirate games. You have to open it up and disable the lockout chip. Unfortunately, you need a special tool to open the SNES and I've only done it with NES so I can't really give instructions.
It wasn't really the battery. Otherwise, the entire save file collection would have shut down.
