Aha i was going to do that but it appears i cannot link pictures with less then 15 posts. :/
I could sort sprites in orders, incorporate different generation sprites into your current generation, example: HG/SS into Emerald for example, I have successfully done first city, mine is called Surrea City, custom ofcourse, have the professor encounter done when i go to head outside without a Pokémon, rival battle etc. this may not seem much to you but bearing in mind i started doing this not so long ago, i can do graphics for you, cutouts etc too.
