View Egg Data

Begin by placing a Pokemon and an Egg in adjacent boxes in the same spot. (For example, place Pikachu in the top-left corner of Box 1 and an Egg in the top-left corner of Box 2.) Hover the cursor over the Pokemon (Pikachu in this example) and then press L/R to move over one box to the Egg. As the switch occurs, pay attention to the lower-left corner where data is normally displayed: it will switch from the original Pokemon's data to that of the Egg. This is the only way to view data about Pokemon inside Eggs prehatching without the use of glitches.

Level Up Unhatched Pokemon

To do this glitch, you must first execute the Pomeg Berry Glitch, which is done by using a Pomeg Berry on a Pokemon with 1 or 2 HP so that its HP loops to 65,535 (displayed as ?35 in-game). Do so, however, with only one Pokemon and an Egg in the party, with the Egg in the top-leftmost slot of the party in the Pokemon menu. After executing the glitch, you will now be able to enter battles and use the Pokemon Egg as if it were a normal Pokemon. It will function as a normal Pokemon - you can view the stats it will have upon hatching, it can level-up by beating Pokemon, it can learn new moves, it can even evolve. This means that you can alter the Pokemon inside the Egg in otherwise-illegitimate ways. For example. Pikachu cannot normally know Thunder when hatching from an Egg at Level 5; through this glitch, Pikachu can. Similarly, you can hatch Eggs with fully-evolved Pokemon such as Typhlosion, Meganium, and so on, inside.

Surf Glitch (Japan-Only)

This glitch allows you to enter the "empty" Mystery Zone that fills the voids in the game's geography, allowing you to obtain the Nintendo Event-only legendary Pokemon Darkrai and Shaymin. (The promotions for these Pokemon have passed, so it is required to use this glitch, only available on Japanese versions, to get them without trading.) You will need access to the Elite Four and Pokemon with Surf and Fly or Teleport. In Aaron's room, face the southern door and use Surf to go through the door. In doing so, you will go through, now easily able to move around to New Moon Island and the Flower Paradise in the game where you can find and capture Darkrai and Shaymin as you would any Pokemon. After you do so, you need to Fly/Teleport elsewhere because you won't be able to leave after that, since the events were not properly triggered. But, otherwise, the Pokemon will function as normal; the only thing to note is that obtaining the Event items for these Pokemon later will not regenerate them, and failing when using the glitch is the same as failing as normal: you only get one shot.

Pomeg Berry Glitch

For this glitch to work properly, you must have a Pomeg Berry and a Pokemon who has not had their HP lowered as much as possible already through Pomeg Berries. (If the latter is the case, the use of HP Ups on the Pokemon will suffice.) Get the Pokemon to a severely low level of HP (1 or 2 HP). Once you do so, in the field, use the Pomeg Berry on the Pokemon. This will in turn cause the data in their HP to cycle back to the top of the counter, giving the affected Pokemon 65,535 HP - over 90 times the otherwise possible maximum in the game.

Increase the Odds of Shiny Pokemon

In the Pokemon series, a "Shiny" Pokemon is one whose coloration is different from the normal: for example, the normally-green Rayquaza is black when Shiny. Shiny Pokemon are exceedingly rare (which is why they are very much valued) - before the release of Pokemon X/Y in 2013, there is a 6 in 65,536 chance to find one, and 12 in 65,536 after: these odds are commonly rounded to 1 in 8,192 and 1 in 4,096, respectively. However, there is a way to increase the odds of finding Shiny Pokemon to as high as 1 in 1,366. You will need Pokemon from two different real-world regions: for example, a Pikachu from the U.S. and a Ditto from Japan. When you breed them together in a daycare, the child (usually the female of the Pokemon being bred) is much more likely to be Shiny than normal, a process commonly referred to as the "Masuda Method".

National Dex/Completing the Sinnoh Dex

Luckily, in this game, all you have to do to complete the Sinnoh Dex is SEE all the Pokemon in the Dex, as opposed to catching them like in previous games. And once you see all the Pokemon, you unlock the National Dex. There are 151 Pokemon in the Sinnoh Dex, but not all the new Pokemon are included in it.
