This is nice tutorial really, I'm making my own hack, so just came here on this forum to see what's going on. And I wanna say, when you hack Ruby, use PokePic for Sprites, not unlzGBA, it's much more easier. When the image is too big, PokePic automatically finds Free Space, so you don't have to use FSF or Hex. But PokePic can only be used on Ruby and Sapphire. And for the Icons, you cannot edit them in Pokepic, you use Rom Hacker XP that I've found here on this page. That's the most helpfull tool for Sprite I've ever seen.
