My Pokemon Diamond Rom freezes up? Help?

Every time I try to use a Pc to withdraw/deposit pokemon, it freezes. Any help would be greatly appreciated.|||did you use cheats? gameshark? etc... that might cause it.|||That's because it is a DS ROM. Those are very unreliable. Using PC and switching pokes causes a great deal of save data change. With the natural instability of DS emulators, I'm not surprised that it crashed.|||Delete the ROM, keep the save file, and download another copy of the ROM, sometimes that happens.|||set up the configuration.
