leiger said:As already mentioned, you need to patch your game. The reason for this is that the EZFlash V 3-in-1(+) stores the game save in a different location to a normal game cartridge. If you were to plug your GBA cart in it would work fine with Platinum on the CycloDS![]()
So, Platinum is searching the 3-in-1 for a save file, in a place where it's not actually stored. Obviously, it finds nothing and thinks that either it's not a Pokemon game or you haven't played/created a save yet.
The patch just says: "Look over there instead!"
