there's a good chance that your battery might be dry. Once that happens you can still play your game but you won't be able to save or migrate Pokemon to the DS games. the only way to fix it is to replace your battery but once it's replaced all of your data on the cartridge will be deleted.

To determine if a film camera is in working condition, you can check the battery, film advance mechanism, shutter speed, and lens functionality. Additionally, you can take test shots and develop the film to see if the images turn out properly.
You can test your battery with a battery tester. If you don't have a battery tester, you could take the battery to Advance Auto Parts and they will test it for you for free.
