I'm having trouble with Sim City Creator on my EZF4. The patcher software gives me the usual "file not known, it be unplayable", but patches the game and creates a savefile regardless. This works for other games. However, when I run it, it tells me "Error accessing save file." and tells me to reinsert the game cartridge. The release info says the save file is 512 Mbit (save type unknown), but the game won't accept the generic 512 Mbit savefile the patcher creates. Help.
