I was so surprised that name was not taken yet, so it's lucky you snapped it up but do be active as Sheep said because PC is cool. Anyways, welcome aboard Magical!
As the others said, you'll definitely know the ROM Hacking boards will become your favorite section of the forums since PC is famous for its hacks. There's hacks you can download to play, as well as tools and resources for making your own. It's got everything to please every kind of ROM hacker so hopefully you'll find something there. Feel free to check out the other parts of the community as well if you need a break from hacking since I know how tense it can get.
Anyways, guess that's it for now so have a nice time and don't hesitate to contact any staff members!
