First of all, what do you mean make? You can only receive one masterball in the entire game. One game. One masterball. One pokemon.
masterball? you can with cheats
theres one materball in team magma/aqua hideout
You can't make your own pokemon.
My mom
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
There is no Pokemon convention in firered.
To get Pokemon firered on PC download a vba and Pokemon firered ROM
Yes there are shiny Pokemon in firered
how did u get mew
No. Poke'mon Master
I'm sorry, but if you have come across a shiny Pokemon and have caught it, then there is no way you can make it a normal Pokemon.
go to eagon,s house before you go to defeat the cipher boss,when you get to his house talk to him and he will give you the materball
