Most likely, because your game's internal battery has run out (though you didn't specify what the exact problem is, e.g. it doesn't turn on). This tends to happen to old cartridge-based Pokemon games.
No, but if u do a code such as "wild Pokemon easily caught, it wont work"
This wont work, but you could try having to Pokemon hold Masterballs and mate them. Hope it works!
your Pokemon hate you so they fried your game chip. sux for you
how does cloning work
The only way to use berries in FireRed and LeafGreen is to berry crush with another FireRed, LeafGreen, or Emerald using GAMEBOYS (DS wont work) and 2 wireless adapters
Dive is not an HM in leafgreen you can't get it unless you trade a Pokemon that knows Dive from ruby or sapphire or emerald but it will not work in leafgreen unless your in battle.
Yes it does.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
Why yes they do!
Not in Pokemon leafgreen only in Pokemon Firered never ever in Pokemon leafgreen And in Pokemon firered it is rare in power plant not available in Pokemon leafgreen?
Pokemon LeafGreen was made for the Gameboy Advance, and so yes, it will work on that system. It will also work in a Nintendo DS that has the extra slot (3DS and later do not have the extra slot), where you can play from that slot or migrate past Pokemon to Diamond, Pearl, or Platinum.
I would say, evolve or somehow obtain a charizard, it work wonders!
