No, you don't have to. You can back it up. :D
Here's what you are to do:
1. Install this. Should be easy pezy, since you have homebrew channel.
2. Backup your current save.(After following the guide at the bottom)
3. Start a new game with OT N.
4. Save at the earliest spot available.
5. Back it up using the same method
6. Send it to me.
7. Restore your save and play.
8. After some days I send you the save with loads of shit(lol)
9. You restore it, and transfer to your game.
10. You have a DS flashcart?Yes. So we will backup your Emerald Save. Send it to me then.
11. Those pokes are yours too with rights.
