Where do you found amulets in Pokemon brown?

There are no amulets in Pokémon Brown. Pokémon Brown is a fan-made hack of Pokémon Red, and while it does introduce some new items and features, it doesn't include amulets.

The Amulet Coin is a held item that was introduced in Generation IV (Pokémon Diamond and Pearl). It increases the amount of money you earn from battles.

If you're playing Pokémon Brown, you can find the Amulet Coin in the following locations:

* Gen IV and beyond: It can be found in the Battle Tower after completing the main story.

* Gen III: It can be obtained from a NPC on the island to the south of Lilycove, near the shore, but only after defeating the Elite Four.

If you're looking for specific items in Pokémon Brown, it's best to consult the game's wiki or a walkthrough.
