I tried to migrate my Pokemon over to Platinum but when I hit "Migrate from Sapphire." I get "Error reading the Game Boy Advance Game Pak's save file. There may not be a file saved, or the save file may be corrupted." The game itself, Sapphire, loads fine with no errors - I have 6 pokemon in my party, more than 6 in all boxes, expect one where I have exactly 6, and I can play it perfectly on my DS. I've tried saving multiple times to see if that was it and that didn't work. Also, all my games are the US version. I have an Acekard RPG, with the US Platinum, and a legit Pokemon Sapphire cartridge.
