That *one* Pokemon? Your name sounds like a mystery. xD
Welcome aboard to the forums! You'll find everything you need for your hack, provided that the first poster has told your great info so you can get started. The regulars there as well as the moderators of the forum can guide you on what you need help with, there's a ton of sticky threads which contain a lot of information for you to know, since you plan to get into hacking.
As Cirny mentioned, the Video Games section is a great place to post in as well, but if you're really into Pokemon, you can check out the sections in the Current Pokemon Gaming boards, and the General Pokemon Gaming boards, both boards contain sections pertaining to each generation of Pokemon!
It's a pleasure to meet you! Cirno, the moderator posted above me can assist you with any questions or concerns! Cid is also there as well, you can also ask him questions as well. Have fun, and see you around the forums!
