I love fakemon. I'm trying to create my own, but I'm not very good at drawing. I have plenty of ideas, though.
I have another question about RPG Maker XP. I want to paste a building onto my map, but the outlines of the building are white because of the white background of the tiles. How do I erase the white outlines?
Well, I can't say about spriting because I'm not much of a spriter... but for mapping, I would advise you to get RMXP and search for already existing maps from the official games to see how they're done. Try doing one of them first, and then editing it, so you can practice xD
