I have a CycloDS Evolution and an EZ Flash 3-in-1, and I've used Rudolph's tools to back up NDS games and saves in the past. Are there any tools available to do the opposite -- that is, to write a .sav to an original DS cart? I searched around but didn't find a good answer. Edit: D'oh, I just noticed that Rudolph's NDS backup tool has a "restore" mode. I guess that's what I'm looking for.
