This code will allow you to modify your next wild pokemon IN THE SAME AREA ONLY after you type in all the numbers in the pokemon calculator. first(if you have the national dex) type in the pokedex number of the pokemon you want and press R and then clear, then type in the lvl you want it to be (1-100) and press L then clear, then you can find the pokemon you want. The other one just makes pokemon sounds, so don't use that one
description states that first number then r and clear is pokemon and 2nd number then L and clear is level.... this is actually backwards type in desired lv (1-100) then press R and hit clear, then Type in desired Nat Dex # press L and hit clear . then walk.

Walls do not crumble when mining Hold L
