Pokemon Emerald [GBA]
Unlimited Safari Zone Steps
Pay 500 to go to the Safari Zone. Go to a grass patch. Stay in the patch and don't walk. Just press the arrow buttons softly like a 90 degree angle and you might catch a rare pokemon without wasting your 500 steps.
Get to Battle Frontier
To get to the Battle Frontier, you must defeat the Elite Four with Pokemon only with your I.D. number. After you defeat them, you will get a ticket from your father to get to the Battle Frontier. The Battle Frontier is another region with fourteen more badges to collect. Additionally, there are seven gyms in the Battle Frontier. The seven gyms are the Battle Tube, Battle Dome, Battle Factory, Battle Arena, Battle Palace, Battle Pyramid, and Battle Tower. Each gym has two badges to collect.
Battle Frontier Advice
When battling in the Battle Frontier, it is vital to bring a Party with few weaknesses. This doesn't mean that you should be bringing weak Pok'emon with few weaknesses. Suggestions include: Ursaring, Slaking, Blissey and Articuno.
It is also important to have decent move combinations. Slack Off is important for Slaking. Articuno can use Mind Reader and Sheer Cold, so that you are ensured a One-Hit KO without fail.
Items also play an important role. Leftovers are a good bet. Brightpowder can be helpful and so can Focus Bands. Oran Berries and Sitrus Berries are not good items for the Battle Tower. Only recovering 10HP or 30 HP is terrible, considering that with Leftovers or Shell Bells, you could be recovering by 20HP to 40HP after every turn.
There are many other fields that I haven't covered. They are up to you. No true advice can be given.
Battle Frontier Excluded Pok'emon
In the Battle Frontier, the following Pok'emon are not allowed to participate:
Berry Master's Wife Passwords
Tell the Berry Master's Wife certain phrases to receive the following berries. You can only tell her one of these each day.
Belue Berry: say SUPER HUSTLE
Durin Berry: say COOL LATIOS
Pamtre Berry: say CHALLENGE CONTEST
Spelon Berry: say GREAT BATTLE
Watmel Berry: say OVERWHELMING LATIAS
Getting Latias Or Latios
After you defeat the Elite Four, go to your house and watch the television downstairs. After you watch it, your mom will ask you what color the Pokemon is. If you say Red, you will find Latias. If you say Blue, it will be Latios.
When you complete the full 202 Pokemon of Hoenn, Professor Birch will call you on your Pokenav and say that he wants to give you a surprise. You can now choose one of the three Johto starters (Chikorita, Cyndaquil, or Totodile).
To get the Magma Symbol (which is required to get to the Team Magma Base), you must go to Mt. Pyre after you defeat Team Aqua in the cove next to Lilycove City.
Mew In Emerald
You can find Mew at World Edge's Island. It will play hide and seek with you. After you found Mew, he will attack you. He will be at Level 30 so be prepared.
Immediately after you defeat the Elite Four, you will go to Professor Birch. He will give the National Dex to you.
Rare new attack for Pichu
Pichu may learn an extremely powerful attack after meeting certain criteria. The attack is called "Volt Tackle". It has a Base Attack Power of 120, accuracy of 100, and 15 PP. The only negative side is that the user takes 1/3 of the given damage.In order to get Volt Tackle on your Pichu, you first need one Female Pikachu holding the Light Ball item. You may then use one of the following to breed with Pikachu: Ditto, Male Raichu, or Male Pikachu. No other Pokemon will work.After finishing the breeding process, hatch the Egg, and inside will be your lovely little Pichu with the Volt Tackle attack! This may be transferred to Pikachu or Raichu if you wish.
The Safari Zone is the same as the one in Pokemon Ruby and Sapphire. The only difference is that after you defeat the Elite Four, two more areas appear full of Johto Pokemon that you could not get in any other games (besides Pokemon Colosseum).
To use the masterball trick when you throw the pokeball hold down and a when you see the ball open hold a and b (this does not work with all balls)
It works with these:
Pokeball level 20-1
Ultra ball 40-1 usually 35-1
