you cant but u get it from the Silph Co. president.
there is only one masterball
for Pokemon there are no codes
First of all, what do you mean make? You can only receive one masterball in the entire game. One game. One masterball. One pokemon.
defeat all rockets and giovani then a man will ive you a masterball
i masterball
No but you can have a friend trade you a Pokemon holding the masterball they got.
You get the masterball when you go and defeat Team rocket
Find it on a route in the grass then use the masterball.
The president of silph co will give you one.
You can't. You only get one without trading it from another Pokemon game.
the masterball is for any Pokemon you want, it can catch them without fail ( it will ALLWAYS work ) . you are supposed to use it for mewtwo though. :P
it roams. u have to get lucky and catch i with the masterball because it flees.
