Well, to be honest graphics are one of the downsides of Emerald, compared to FireRed. I mean I didn't see wanting to change as a bad thing necassarily but I suppose you could be right. Not only is there the advantage of secret bases, but also contests, the PokéNav, an RTC and berry trees, etc. etc. etc. Seeing as progress on Dark Cobalt has slowed down a lot recently I'm not 100% on which to do. For now, I'll stick with FireRed.
