Pokemon Theta Emerald Ex rom
When focusing on the main objectives, Pokemon Theta Emerald Ex is about 16 Hours in length. If you're a gamer that strives to see all aspects of the game, you are likely to spend around 50 Hours to obtain 100% completion.

Pokemon Theta Emerald EX is a romhack of Pokemon Emerald. It is a romhack aiming to challenge the player more than normal Pokemon games, and it has plenty of features and changes including a max level of 250 for your Pokemon.

Go to Route 104 where there is a flower shop, enter it and talk to a girl there where she will give you the Wailmer Pail. Then fly to Battle Frontier and head right where you need to surf and get to another part of land on the right. You will see a strange looking tree there where you can use the Wailmer Pail.

After that surf south and to the left where you will enter the Training Cave with lots of unique and high level Pokemon. Use Repel to get through quicker. At the end of the cave is a mysterious ring where you can battle and capture Mewtwo.

Riolu is a Friendship evolution and it will evolve with 220+ Friendship upon level up.

There are many ways to increase friendship level -

1. Catch Riolu in Luxury ball or Friend ball.

2. Use vitamins on Riolu, like protein, iron, calcium etc.

3. Win battles using Riolu.

4. Give Riolu the item Soothe Bell to hold.

5. Keep Riolu 1st in your party when you travel.

6. Feed Riolu it's favorite berries.

  1. Make sure you've beaten the 5th Gym (your dad's) and spoke with your Mom to get the Mega Armlet.

  2. Equip the Mega Stone to your Pokémon.

  3. Get yourself into a battle, pick "Fight", Press Start (a sound effect should play, that means that everything's working correctly) then just pick an attack and use it.
