You need a Connection device, a new pak of Firered/Leafgreen and another game boy advance.

first:open you original game you played every time with the new one on the other gameboy advance.

In the new: you first choose charmander then trade it

Then choose squirtle and trade it

Then bulbasaur and trade it.

then you can start the new game on the new pak.



Hmmf! Hope this can Help Lots!
