Yoshi's Island doesn't work correctly in later levels, and somebody already mentioned Cooking Mama earlier this thread (slowdowns in some minigames). Pokemon Trozei has some slowdowns, and the cursor is transparent and almost impossible to see. Same with most of those other listed games: slowdowns, problems later in the game, etc.
I haven't tried all of those, so there are bound to be some on that list that actually are fully playable. However, out of the two hundred or so that I've tested, the only one that seems to work perfectly is Digimon World DS - but I haven't finished it, so wouldn't know for sure.
