Hello from me to you too! Always great to have more faces around.
As the others already covered, our ROM Hacking section has got everything you need in the hacking department, whether it's hacks you want to play or tools for making your own. I'm not a real hack expert, but someone else other there would be glad to help you if you need it, and for the more serious questions Spherical Ice and Christos are around if you need them.
Hope you enjoy checking out not just the hacks but everywhere else as well, since we love catering towards so many tastes in one place. Enjoy your time with us, and I do hope to check back with you later.
