Is it possible to delete your data in Pokemon Dream Radar?

Question

I want to get another Tornadus for my game. What I'm trying to do is get Landorus in Pokemon White, since I already have Thundurus. However, the original Tornadus I had, I already sent to my Pokemon Omega Ruby months ago. So, is there any way of deleting my file of Pokemon Dream Radar WITHOUT me having to delete it completely and buy it a second time?

Answer 1

This forum seems to indicate you can delete the save data and re-download it without having to purchase a second time: http://www.gamefaqs.com/boards/661226-pokemon-black-version-2/64285940
