Yeah I have the same problem! I beat the elite 4 without finding any of the added pokemon except a rare glameow and a level 70 jirachi. I use NO$GBA if maybe thats the issue? It's just weird because perfect platinum works fine and I have 114 pokedex entries before the 3rd gym, but for this one I only have 90 with 8 badges . I even tried looking in the grass over and over again but still I didn't see any newer ones. I did enjoy the higher difficulty for soul silver though, it was fun but I wish I could have the waay better experience that the platinum one is giving. (It's waaaaaay more fun being able to capture all pokemon without the hassle of trading, events etc..)
