I started playing Pokemon leafgreen today and it said that the 1M subcurcuit board wasnt installed. This is not a ROM but a physical copy. There is a save file but it cannot be played. I cant save over it, an error message comes up when I do: "Save error, please exchange the backup memory".

No I have not modded the advance. I did plan on throwing a font light in there but that will be a while. I will clean the cartridge contacts and see if it works then.
