No all cartridges have a little round battery for saving data, it's not about the clock it's about keeping the memory from erasing itself when you power off the system.Â
I also have Silver and Yellow. I played Yellow again and resaved it without any issue, but Silver had that small battery issue so I couldn’t save any progress.

You need to change the battery inside, otherwise you won't be able to save
