Hello, I'm the Time Travel Expert around here that cannot make up his mind on his avatar and signature.
You will have to download PokeSav.
If you have access to your save file, then load it. If you load it, and it dosen't work, then convert it into it's raw format.
If you have an Action Replay, skip loading the save file, and export ARDS Codes after adding the pokemon where you want them.
If you don't have access to your save file, and you don't have an Action Replay, then you cannot put the pokemon on your cart at this time.
Reply to this if you have a DS flashcart, but don't have access to the save file.
