You're actually partially right about the layers. There are about 4 layers that are all accessible via unlz gba. They are the animations when the titlescreen is like blinking. If we don't remove/edit those 4 layers, the color's gonna be messed up in between the blinkings. In order to remove those animations, we have to replace them with 4 frames of transparent templates, or if we're more of hard workers, we'd edit the animations. My designing is far more advanced, unfortunately, than most of the tutorials on PC (not trying to boast.) The ones done by DawnRyder only touches on editing some parts, but my version is completely redesigning the titlescreen, although I still use the backgrounds provided by HG/SS cuz I'm lazy, but if you ever look at LoA, SL, Pokemon Illusions or even light platinum, the titlescreens are redesigned in every inch. I believe you would be able to do such complicated things, that's why I asked you for assistance :D
