Update!
Emerald Patch has been released!
What's new:
The DS-style 64x64 Pokémon Sprite Patch ported over to Emerald, of course!
Corrected gender sprites for Rhydon, Goldeen, Seaking, Ledyba and Dustox.
Unfortunately, an update always has bugs. Pelipper's back sprite (both normal and shiny) is partly transparent. I'll look into it soon and a fix will probably be up and running when the MrDollsteak fix is released for FireRed.
And another little bug: both the shiny front and backsprite of Milotic are glitched. But once again, have a try saying 'yo' to a shiny Milotic before it dives in the depths of sea to be never seen again...
