move tutoring
you can use heart scales at the move tutors house in farllabor town in ruby sapphire and emerald......hope i helped
In Pokemon Emerald Heart Scales can be found in various locations. However the main source of Heart Scales is Luvdisc which very commonly holds them.
you have to go up to rocks and press A
Luvdisc will always hold them, catch a bunch of them.
Heart scales are only in Pokemon emerald, ruby and sapphire but you can get one if you trade a heart scale from ruby or emerald or sapphire to leafgreen then take it but it will not do anything in the game.
I only found heart scales in Ruby, Sapphire and Emerald but I'm not sure of the other games.
Luvdisc sometimes is carrying them when you catch them, so catch lots.
You trade them in to the move tutors house which is on the far left side of fallarbor town
Heart scales are usually found underwater, also randomly luvdisc can hold this item so if you want more catch a lot of luvdisc.
Well heart scales do not have a code.
emerald green
None. Heart Scales are used to pay the move tutor in exchange for re-teaching moves to your pokemon that they have forgotten.
