Hmm... I guess you're right. Chaos was a bit of a spark, although I really think he has way too much stuff to do. Titlescreens are not my forte. I don't even know how to do scene pixel art, considering what I made as my first. Which means I'm zero there. But Chaos said he wouldn't do X/Y sprites, so I'll help you there.
sorry I got all the sprites from Choas Rush's resource. If you still wanna help me, can you make a Title screen pic with a suitable background,Arceus and the Pokemon Logo named Pokemon The Legends of Arceus no bigger than 240*160 as one of the pic shown in the link you previously gave me?
