Now that Gen IV is complete, I'm going to make some changes to the rules for people that want to help:
*Anyone can help. You don't have to PM me anymore. Just post a sprite and if I like it, I'll use it.
*If you're resizing a Pokemon from Gen I-III, make it around the size that the Pokemon is in R/S/E
*All Generation I front sprites have to be resized from this sheet: http://i49.tinypic.com/bgwch2.png
*All Generation II front sprites have to be resized from this sheet: http://i49.tinypic.com/21446km.png
*All Generation III front sprites have to be resized from this sheet: http://i48.tinypic.com/bhbox.png
*ALL backsprites must be from HeartGold/SoulSilver, recolored to match the front if necessary
*You are allowed to use custom sprites for Generation V Pokemon
*You are allowed to make a custom sprite for Rayquaza because all of its official sprites kinda suck
This project is great, hopefully more hacks will use these sprites, they're great.
