I've been studying Emerald some... well, a lot. :D
I had some things for your Useful Emerald Stuff thread, which includes:
How to remove the Boy/Girl flightpos chooser for Littleroot, and some other map-related things
How to choose what Pokémon Wally uses to fight with
Also, I'll tell you how the bytes of Wally's Pokémon and the opposing Pokémon work (even the level can be changed!)
