Thank you very much. This Nameless Sprite Editor thing is very helpful.
That brings me to my next question. I'm trying to add new legendaries to the game, and a couple events allowing the player to acquire unique Pokemon. For example, I plan to make several new Regis, add some legendaries from older games and a few that are unable to be acquired. For this, I have to be able to create waiting legendaries. How would I go about doing this? Is there any way I can create a new overworld sprite without overwriting another one, and would it require the use of scripting?
