Is there a way to remember old moves in Pokemon black and white like using heart scales platinum - how do i it?

To remember old moves in Pokemon Black and White, you can use the Move Reminder. There are two locations of Move Reminder:

- Mistralton City Pokemon Center - located on right in the Pokemon Center.

- P2 Laboratory

- First, talk to the old man behind the desk and pay 1 Heart Scales or one gold bottle cap per forgotten move. If this is the first time you are using his service, he will ask you if you want to be reminded what a Heart Scale is.

- After paying, he will allow you to pick one of your Pokémon and teach it one of the moves it has learned in the past.

Alternatively, you can also relearn moves by obtaining the TM of that move and using it on the Pokémon. However, remember that not every forgotten move can be learned from the Move Reminder or TMs.
