Have you try updating to the latest firmware update? Do you have cheats enable? Perhaps too many cheats (or maybe a few that are conflicting with each other?)
Hello mate, Yes I have the latest firmware and no cheats on any of the games.There my kids DS's one has the M3 Real card and it works well on that just the Edge card will not work.Firmware 1.43.
Not sure what seems to the problem. I assume this does not happen in other games as well? Have you try a different back-up of the game? Perhaps that back-up was a bit flaky when it was being made.
Clone wars has an anti piracy system in the code, it does not work with the edge card as yet, you will have to wait for another new firmware see http://www.gbatemp.net/index.php?showtopic=129418
