Hi there! The thing you're talking about is a patch someone once made, I believe it was only for FireRed and I'm not too sure where it can be found now...
If you find someone whose hack uses it, perhaps you can ask them where they found it? Most people who have it used the patch, it's unlikely EVERYONE coded it in, themselves xD
I'm fine, thank you. Well you can either try submitting the thread or simply show me the screenshots in a PM and I'll let you know if the meet the requirements. :)
