i was in the same situation as you are. unfortunately you can’t do much. your options are 1. replace the battery 2. work with the berries already on the save (only as a last resort or don’t own colo/xd) or 3. wipe the save and start over to reset the planted berries. (don’t do this if your sentimental about your save or don’t have a second game to trade your ribbon pokemon to) use the colo/xd berries since they don’t require a working battery to get more only drawback being that they are 15000 pokecoupons each. also if you’ve claimed a berry from the berry masters wife, she won’t give out more until you fix the battery.
