OK. I've spent the past hour and a half looking for the code I'm about to ask for, and I've had no luck finding it.
I've got Baka_Kyuubi84's "Mega Exp. Code," which works great. It's a good code for when your Pokemon are higher levels. However, I'm starting a new game, and the amount of experience you earn is... well, absurd! I evolved my Chimchar before I even got to Sandgem town!
Basically, I need someone to tell me which one of these values will make it so I've got approximately "double experience," similar to the HG/SS code. It's perfect for me, since I like grinding, but not too much grinding. I'm guessing it's "0001FFFF," but I'm not sure what the heck I'd have to put in to change it to what I want.
I've got a feeling it's going to be a while before this is responded to, so I'm going to play around with it myself, so if I find it, I'll be sure to post it here!
Also, I've got one other question: The code for "shiny encounters," does that work, or is it supposed to work, when you pick up your starter? Because it didn't work for me.
Much thanks, everyone.
