Pokemon LeafGreen how to infinite master balls?

Answer 1

lol thats so easy, i got all the pokeballs as key items in my inventory but im not telling you how. I will give you an awesome site for lot's of things you want though-

It has walk through walls, any pokemon you want, buy pokeballs in mart, infinite safari time...ect. ect.
You can only get one Master Ball per Pokemon game, but I you REALLY want more than one, I suggest having two games, then trading a master ball over from the game you could care less about, starting that game over, then trading the Master Ball over to your good game, then starting that game over... and so on. To speed things up a little, you could use a high level Pokemon to do the trading so you can whup all those annoying trainers that pop outta nowhere and get to saffron faster. OR, If you have Pokemon RUBY, SAPPHIRE, or EMERALD, go to lilycove, and try at that lottery ticket in the big store there. there's a small chance that you can win a free Master ball there.

Answer 2

You can't get infinite but you can put it on a Pokemon then duplicate it. I have done it.

Here is an simmilar example to how I do it.
