You can transfer the .sav file from the "Battery" file in No$GBA to a DS Flash Kart and replace your original .sav file with the .sav file from No$GBA.

If you have another copy of Pokemon Diamond or have Pearl or Platinum with a different DS, you can trade between systems and have one of them start a new file and pick the Starter you are missing to trade to your primary Pokemon Diamond file. It'd be easier to have a friend help you as well.
