It depends on which version of the game you're playing, in Diamond and Pearl only 85h is used, which is used for where the Pokemon was caught/received, for example whether it was caught in the grass, received as a starter, hatched from an egg, etc. From Platinum and on, in addition to 85h 44-47h are also used, 44h and 45h being used only for eggs and being where they were received from, Daycare Couple, Riley, etc. 46h and 47h are for the met at location, meaning where you caught, received, or hatched the Pokemon. A Pokemon in any of these three games will pass the legal check on Battle Revolution and WiFi and what not without bothering, and will look perfectly legal at a glance as long as nobody Pokesavs it and checks the hex values you wouldn't notice a difference. However, in Heart of Gold and Soul of Silver they're vital as the current version of Pokesav doesn't include Johto and Kanto locations in the drop boxes, so you have to set the met at location to Faraway Place and manually imput the hex values for where the Pokemon was met, you also have to select the regular Pokeball from the drop box, no matter what Pokeball it will actually be in, and input the hex value for the Pokeball in 86h. The reason for this is mostly compatibility I assume. The Sinnoh games don't have Apricorns nor Apricorn balls, they also don't have the Johto and Kanto locations, so the hidden hex values are used to make it so a Pokemon from Johto caught with a Heavy Ball will properly display in Heart of Gold and Soul of Silver, while if it's traded to the older games they'll simply ignore them and will display the Pokemon as being caught in a regular Pokeball and coming from a Faraway Place.

From the first post.

Are you sure you're putting it in the 46h slot and setting the met at location in the drop box to Faraway Place (3002)?

Scaurab, a golden beetle, the evolved form of Pinsir who is in dire need of an evolution to make him more on par with Scizor and Heracross. A steel/bug type like his original counterpart Scyther's evolution. Sporting high attack, defence, and HP he'd be built for tanking. Larger and bulkier than Pinsir, the pincers would be removed, instead being given a second pair of large powerful arms, on his back would be a skull pattern formed by blue jewels as hard as diamonds. The shiny form would instead be a shiny black with red jewels. Points to anyone who can figure out the name origin, and the short story which inspired the design.

Johto (Heart of Gold) or Johto (Soul of Silver) depending on which version you're playing. Question of my own since I'm not positive, and don't recall seeing it asked already, would the secondary "starters" received after getting all 16 badges (the Hoenn and Kanto starters) have an 85h of 18, or 0C like the actual starters you get from Elm at the start of the game?

Just a thought, but it seems possible to me that they could still include Pokemon following you, but give you the option to choose whether you want them to do so or not, in which case it makes sense they would make it a point not to have any Pokemon out since Zorua and Zoroark are the only two we're supposed to know about so far.

Read through the entire thread and didn't find the information I was originally after, so decided to play around with the hex values myself, didn't take too long as it turns out. Thought I'd share it in the event anyone else is interested, the hex values to create an egg received from Primo (the guy in the Violet Pokemon center, gives out Mareep and Wooper eggs, and some Pokemon yet to be revealed, if you give him the right secret phrase based on your normal trainer ID) are 44h: DE and 45h: 07.
