Oh, ok... :)
Lol, I already said it you don't have to Index, or maybe you don't know the meaning of Index? Yes submit them in 256x64... :)
Index is a method before Wichu's Sprite Editor was made look up on UNLZ It won't accept sprites if it's not on 16 colors, and Index with the outline as the background color and the background color as the outline and they merge it together using paint, and maybe if you're confused because of my tutorial because, I used the 256x64 Zoroark Sprite it was just an example you know.... :) That also happens in NSE 2.x... :)
