>>47528447Buy a mega memory card and back up your save, they’re like $50 but a small price to pay I suppose. Reload it once you replace your battery and bam, got another 15 years AND your old save.
>>47530066You’re good, only gens 1-2 have their saves tied to internal battery life. Third Gen games have time based events such as berries tied to battery life but the saves are fine. My emerald battery died awhile ago but my save is still intact.
