Hi people, I have been toying with the idea of expanding the Crystal Legacy romhack for a long time now. The plan is to include the Orange Islands, Crystal Onix, changing a few things about the legendary bird trio's first appearance, etc.

I basically have organized all the changes I want to make, but the thing is that even though I am experienced with programming, I'm currently stumped as I can't find the right tools for the job.

Can you point me to the necessary tools for modifying a Gen 2 rom? Or even a tutorial as I couldn't find any.

Thanks!
