Allow communication between emulator on Wii and real DS #204

The Wii was/is able to do DS Download Play stuff with DS'es, and when I was scrounging around I found this. I know the protocol that the DS uses is colloguially called Nifi (Nintendo wifi) and that it's a slightly modded protocol from what's standard, but I can find little to no information about it, besides a bunch of people saying no one really understands/has used it in any way.

It's probably not super useful, but I can think of one use: Unlocking the DLC in Dragon Quest IX. In Dragon Quest IX, you were supposed to go online to unlock all the post-game quests, or you could connect to a DS that had the DLC unlocked. It's fairly simple to unlock the DLC if you have access to the save file, so you could theoretically edit the save file for the emulator to unlock the DLC, and then use the Wii's Nifi functionality to connect to a real DS who doesn't have the DLC unlocked, which will then cause the DS to edit the save file and unlock the DLC.

I might try working on this if I can figure out more about Nifi, and if I can become more experienced with how emulators work, but I'm also not super experienced with C, so I'm probably not the best person for the job.
