Major List update. The games also have the amount of DSi Points you need to buy it. Also, a little later on today I'm going to go over into the DSi Shop and browse which games have Wi-Fi or not, since most on the list say they don't have Wi-Fi, I'm gonna do some first-hand double checking, instead of using Wikipedia. Additionally, the list was getting a little clunky IMO, so I spaced it out. If a few people don't like it to be that way, I'll change it back. Let me know.
As far as I know, the games probably all cost the same, but for reference, these are North American DSiWare prices.
Also, I can't find Dictionary 6 in 1's price anywhere. Can anyone tell me what it is?
