Welcome to the PokeCommunity, Shedinja! Better get started on that hack, right? :D
Do you have all the tools you need? Do you need any help on some things? Head on over to the Emulation section of the forums. :D You'll pretty much find everything you need from mapping help, scripting help, and even form a hacking team if you like. Many members in that section, as well as the moderators, are more than happy to answer your questions and help you with anything hacking. There's so much to do in that section.
And, once you're done viewing that section, check out all the other Pokemon sections we have here. Maybe you're interested in the games, the Anime, the TCG, and more. We even have discussions for the upcoming new Black & White games coming in the Fall. THERE'S SO MUCH TO DO. :)
But imma let you explore what PC has to offer, ok? If you'd like some guidance around the forums, you can check in the Adoption Center and contact a mentor! :) Or you can just PM myself or Snivy if you simply have a question about the forums. ok! So, I shall see ya around then! :)
