My idea offer of hack

Hi. I would like to show you my idea pokemon hack. (My english is not good, so i use basic words)

My favorite pkm version is "crystal". I can win "johto" and go to "kanto". I`m looking for hack who I can win "kanto" and go to "johto" --> crystal inverse

Maybe, exist anywhere this hack? (crystal hack / firered hack ? )

um to help from what your saying to me your looking for a game were you start in johto and go to kanto as well? try and use pokemon crystal silver or gold if not then try to use a map editor to add in large maps of regions you can add but its alot of work.
