It's impossible, but if you do want master balls, go back to ruby or leaf green or fire red or emerald. Get a master ball, give it to a Pokemon to hold and then migrate it to heart gold. Repeat this process as many times as you want but it will take some time because you need to DO IT ALL AGAIN!
THERE ARE NO CHEATS IN HEART GOLD OR ANY POKEMON GAMES EXCEPT BLUE WITH A Surfing PIKACHU AND LOADS OF RARE CANDIES BUT THERE ARE TRICKS AND ACTION REPLAYS.

A Poké Ball can't be changed into a Master Ball.
After you beat Lance, go back to professor Elm and talk to him. Then, he'll give you the master ball! (You can go to pokemon.marriland.com.)
