Here's why:
* Game Mechanics: Master Balls were introduced in later generations and were not part of the original Pokemon Emerald design.
* Limited Resources: The game developers likely decided to keep the focus on catching Pokemon with other Poke Balls, encouraging players to strategize and utilize different methods.
How to get Master Balls in other Pokemon games:
* Trading: If you have access to later generation games (like Diamond, Pearl, Platinum, etc.) you can trade them over to Emerald.
* Cheats: Using cheat devices or save editors allows you to add Master Balls to your game, but this is considered cheating and can potentially corrupt your game file.
Focus on other catching methods:
Instead of looking for Master Balls, enjoy the challenge of capturing Pokemon in Emerald using the various Poke Balls and techniques available to you. Experiment with different strategies and see which ones work best for you.
