"Sevii Isles 8 and 9 are locations which are not accessible through normal gameplay in Pokemon FireRed and LeafGreen ... it seems as if they are abandoned areas left over from the beta of FireRed and LeafGreen"
There is no 8island on fire red sorry.
U gotta go to a Nintendo event. Sorry.
I advise doing all the stuff on 1,2,3,4,5,6 and 8island and completing your pokedex and getting the aurora tickets and stuff like that
You'll need an Aurora Pass. Go to the Poke Mart and there will be a clipboard. Put "Link together with all" on the clipboard and talk to the guy in Green at the Pokemon center.
Slowpoke is not in firered only leafgreen can get it trade one to firered to get it.
Firered and leafgreen both can catch different Pokemon but there pokedex is the same, here is some examples: magmar only in leafgreen not firered, oddish in firered not leafgreen, ekans in firered not leafgreen, bellsprout in leafgreen not firered, pinsir in leafgreen not firered.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
There is no Mew in FireRed or LeafGreen.
trade it. There are no houndours in firered.
in firered
Norman is not in firered.
Does do not exist in firered.
