Thought this was interesting... http://gbatemp.net/index.php?showtopic=216963 for those of you who dont frequent the GBAtemp forums, the guys over there are making a DS emulator for the wii. It's still in development but seems to be coming along pretty well right now. Read about 10 pages and they had the file browser and a cheat system compiled within a week. that was back on March 30th-ish. I can only imagine how far it is now.
