Are there any records of the RAM in these going bad/corrupt? Mine won’t save a single thing. I’ve replaced the save battery once already but I suppose it’s possible I’ve gotten 2 bad batts. Thing is, I just started a game, saved, then powered my GBC off and on within a split second and the save didn’t hold. In my experience the save would still hold within that timeframe even if the battery was dead. It’s as if the data never got written to RAM at all.
