Hello there, I'm an expert in Pokémon evolution mechanics. Let's dive into the process of evolving Yanma.

To evolve Yanma into Yanmega in the Pokémon games, you need to trade it while it is holding a specific item called the Shiny Stone. Here's the step-by-step process:


1. Acquire a Shiny Stone: First, you need to find a Shiny Stone in the game. The availability of this item can vary depending on the game version you are playing.


2. Trade Yanma: Once you have the Shiny Stone, give it to Yanma to hold. Then, initiate a trade with another player. It's important to note that the trade must be completed; simply offering the trade is not enough.


3. Evolution Complete: Upon completion of the trade, Yanma will evolve into Yanmega.
