Is there an emulator out there that can emulate the DS's wifi signal? Specifically the tag mode. I'm thinking for Dragon Quest IX, it has that tag mode where you set it to 'canvas for guests' and then it sends out a signal and hits any other passing DS's with some information. Now, presumably you would need a laptop capable of sending the signal but those are common now. Is there an emulator that can do it? If there was, people could set up sav-swapping and trade their save files, it almost be like the 'real' tag mode...just...via proxy.
