I have seen many say that the graphics for SMS are superior, but it seems to merely use a brighter palette, because if I recall correctly, it can actually display less colors at once. In my opinion, the games often look like Commodore 64 graphics (slightly elongated pixels) colored with the MS Paint palette. Not very pleasant. Of course, that's not to say that some developers didn't effectively utilize the available features for fairly competant visuals. Then again, I realize that the SMS didn't have a large degree of third party support for most developers to demonstrate what it was truly capable of most of the time, but examples would be nice. The FM sound option is also interesting.
