Well, I'm not sure whether this should be in the Emerald section or the Diamond/Pearl section since this involves both, yet surprisingly doesn't involve Pal Park.
So I just got a used copy of Emerald today. It could save and everything, so I assumed the game was fine. Then I start up Pokemon Diamond, and it doesn't have the Migrate pokemon from Emerald option. I figure that's fine, since it's a brand new file in Emerald and the trainer doesn't even have a pokemon yet. Then I start up Emerald and it says the file was deleted. The exact quote was "The save file has been erased due to corruption or damage."
From that point on, whenever I created a new save file on Emerald, it would be deleted once I started to play Pokemon Diamond with Emerald in the GBA slot. I know it's not my DS or my copy of Diamond since my copy of Fire Red has not had this problem. And Emerald works perfectly as long as I don't play Diamond. Has anyone seen this error before, and does anyone know what I can do about it?
EDIT: I now suspect that my copy of Pokemon Emerald may be inauthentic and not produced by Nintendo, which would explain why it doesn't work.
