Ingame, CB sleep talk doesn't work as it is on netbattle. Ingame, say Zapdos is asleep with cb, if it uses sleep talk, it would pick a random move but it will ONLY stick to that move. so if sleep talk picks Hidden Power Fighting first, then it picks something else like tbolt, the game would say "But It Failed!". And if you pick CB sleep talk even before you were put asleep, it will always say "But It Failed" during sleep. This doensn't happen on netbattle though; sleep talk picks whatever move even with CB.
Also, I noticed that rapid spin can still be removed even if the enemy has a substitude on. I tested this with a wild ditto in emerald after it transformed to my claydol. I send in skarm and put some spikes, I sub, but then it used rapid spin and it removed spikes. In netbattle, this doesn't happen as sub ALWAYS blocks rapid spin. Just posting his cause I noticed some stuff ingame and I wanted to know if they were glitches by Nintendo or if its a bug here on netbattle.
