I haven't really noticed any major glitches, but there are quite a few graphical glitches in this game, I guess from the upgraded system, and also possibly because I'm playing on the original DS. There appears to be some kind of lag in the graphics quite often, for example the one in Nimbasa that has been mentioned before, and also when my brother is in my entralink, switching between a pokemon's two profile pages also causes several moments of lag, which scared me slightly when it first happened.
