I'm sorry, I've searched through this thread quite a bit (admittedly, I didn't go through all 826 pages, but I went through quite a few!) and I haven't found an answer to my particular question.
I want to replace Brock (and all of the gym leaders, really) with gym leaders I have made myself. Different pokemon, different types, different moves, all of that.
I have A-Trainer and Advance Map and XSE and all of that good stuff, but I haven't found a walk through on how exactly to do this. Could somebody help me out?
