How to Use Mega Evolution in Moemon Star Emerald

• Make sure you have a Mega Bracelet in your inventory.
• Equip your Moémon with the correct Mega Stone.
• During battle, select Attack, then press Start (or whatever key you’ve assigned).
• Use a move, and your Moémon will Mega Evolve.

Mega Stones are scattered across the region, appearing as sparkling spots, or they can be obtained as gifts. You can start using Mega Evolution after getting the Mega Bracelet from Steven on Route 118.

Known Bugs

• Time-based events follow your device’s clock instead of the in-game room clock.
• Important: Backup your save before using the Battle Frontier facilities or Battle Tents, as they can occasionally wipe out your PokéDex data.
• Once a Moémon reaches level 100, it can no longer receive EVs through training due to Gen 3 mechanics. However, Vitamins still work, and they are uncapped.
• The Search by Name function in the PokéDex is currently broken.
• The PokéDex Order function sorts listings incorrectly.
• Rare Candies may show a +0 stat gain, but this is just a visual bug.
