Welcome to PC, Candice! We're all huge Pokemon fans, so you're not the only one! :) You've joined in one of the most amazing Pokemon forums on the web, and we're also the friendliest as well. :D I was about your age (8 years old, that is), that I started playing Pokemon, and even though I took a few breaks, I'm still obsessed with it. xD
I haven't heard of Turquoise. But since you're interested in hacked roms, we have a full library of them. :D Visit the inside the Emulation section of the forums, and you'll find lots and lots of them, even popular ones like Liquid Crystal, Ruby Destiny, and Flora Sky.
I hope you get settled here at PC, and hope you become an active member like us! Have a great time here! Be sure to check out the Adoption Center and/or PM us grass-type moderators (me & Snivy) if you have any questions! Nice to meet ya. :)
