Duplicate Items

To perform this trick you must have a Pokemon that knows 'Thief', and a Ditto. Enter a double battle with a Ditto without an item and a Pokemon holding the item you want to duplicate. Make Ditto transform into the Pokemon holding the item. Switch the Pokemon holding the item with the Pokemon that knows Thief. Use Thief on Ditto. Win the Pokemon battle. The Thief Pokemon now has a duplicate of the item.

Phantom Communication

When in the Union Room, stand where your friend spawns. When he or she enters the room, it will not notify you or show them, but on their DS it will show you and it will have a notice. When your friend communicates with you, it will say that your friend wants to talk, but on your DS you are the only one in the room.

Traps and Spheres Duplication

Go to Jubilife TV and do the steps to get a picture of your Pokemon. You must approach the photographer from the left or right side. If from the left, when asked to choose Pokemon, press Left or Up. If from the right, press Right.

Strange Areas

Two people required for this trick. When in the underground, get some traps or spheres then get to the surface and save the game. Go back down and set your trap anywhere. Set the other person to COM and take the trap or sphere from ground. Turn your game off but leave other person's game on. Save other person's game. Both the people should now have the same trap or sphere.

Walk Through Obstacles

Get on your bike and turn on the fast gear. Go to any town or route. If you are in a town like Solaceon Town, go to the very top of the city. While riding all the way down through the city, rapidly press Left and Right. Your character should appear to be spinning while moving forward. If done correctly throughout the whole ride, the next route you are heading towards will be glitched with either an invisible wall, a white void, or a black void. Your game may crash. Sometimes the void may be walkable. You can use this glitch to find new ways to capture the event pokemon Darkrai and Shaymin without the events.

Make it rain in Solaceon Town

Look on your map. Go to a place that is close to the end of the map, where there are areas you cannot reach or go any further. Ride your bike through a Route (rather then a city) and encounter some Pokemon. Defeat some, run away from some, catch some, or damage a Pokemon's health once and run away. As soon as you hit the water's edge or an area that cannot be run through (for example, trees or a stone platform), save the game. When you return to your game, instantly press the direction facing the obstacle that could not be walked or ran through. You will start running through the objects. The top screen will indicate that you have reached a place called 'Mystery Zone'. There will be faint music playing, like that of the area where the PalPark is located, and you may bump into something. Just keep on holding the D-pad and you will eventually get through. You will soon reach the game's limits; where it just shows infinite black abyss. This is very difficulty to do, and will require multiple attempts and a very long time. Note: This is not guaranteed to work with every game. also, you cannot use your bike or open the menu. This is not recommended at some points in the game; use with caution.

Professor Rowan talks on PC while captive

Go to Solaceon Town. Get on your bike and ride it at its fastest speed to route 210. Go to where it rains. Go a little bit in it then ride into Solaceon Town. It will look like it is raining.

Step counter

After you defeat Saturn at Lake Valor, go to Lake Verity. You will find out that Professor Rowan is being held captive by Team Galactic. Go to a Pokemon Center and go to Rowan's PC on the PC. Professor Rowan will be talking to you.
