So, for whatever reason, I had the urge to replace Lyra's sprites in HeartGold. Only problem is... I'm clueless. I have replacement sprites ready to go, but I don't know where to replace some of them, or how to. I can edit the overworld sprites with a combination of BTX Editor, and some program called kiwi.ds, but I don't know which files are Lyra's sprites. I have most of them down, but I need the rest of them, and searching through over 800 files isn't exactly thrilling. After that, I need to know how I can replace the in-battle sprites (the animation where she throws out her Pokemon), her trainer card sprite (I forget if there's a Pokeathlon variant), her mugshot, and character select sprite (if that's even possible...). Any help is welcome, I just wanna get this done.
