The only way to get one would be to trade it from Ruby or Emerald.
not at all.
we don't get groudon in Pokemon sapphire. we get it in only ruby and emerald
You'll need to trade for it or transfer it from the older DS Pokemon games.
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.
You have to trade across from older versions or from someone willing to trade
you cant but you cant but if u trade it from heart gold to platinum then you have a groudon
A master ball can catch any wild pokemon.
To get Pokemon firered on PC download a vba and Pokemon firered ROM
Yes there are shiny Pokemon in firered
Groudon, is found in Sootpools city. After you defeat team Magma(Or is it Aqua...)
I think you have to transfur from ruby version or something, I havent done it yet.
