Do you know what your Secret ID is?

For the shiny question: if you have free reign over the Trainer ID and SID, a quick way to do it is to set the Trainer ID equal to the PID divided by 65536, and set the Secret ID to the PID modulo 65536 (meaning, divide by 65536 and take the remainder). This will look "fishy" to someone examining the Pokemon data directly (since the PID and the trainer ID are an exact match), but it's still legal; it's technically possible, if unlikely, for such a thing to exist legitimately. If you want something a little more robust, try this quick script - enter the PID of the Pokemon in, and it'll give you a Trainer ID and SID to use that should result in a shiny. For the Pal Park question: it depends what game brought the Pokemon over. If it was migrated via Diamond/Pearl, all hidden hex values should just be 00s. Otherwise, set 46h to "37" and everything else to 00.

OK, so I understand how each of the eight types only shows up in certain situations, but I'm curious as to what distinguishes them from each other internally - how you can tell them apart. Like, for instance, Type1/Normal DS is "A-B-C-D", and Type5 is "B-A-D-E". But, what makes a given PID/IV combination a Type1 and not a Type2 or Type3 or etc.? In fact, what do those sequences of letters mean in the first place? Thanks for any help you can give Edit: So I did a little more digging and finally got my answers. Turns out the explanation isn't as simple as I had hoped; the letters actually have to do with the order in which numbers spat out by the PRNG are used in generating the PID and IVs. (This is also apparently why eggs don't have PID/IV matching problems - they are generated at separate times so any number of RNG hits might have occured in between.) Well, anyway, found my answer so there's no need to keep this thread going.

I remember reading somewhere (can't remember exactly where now, though) that Type 2 PIDs are considered invalid for XD/Coliseum Pokémon. Try picking a Type 1 and see if the legality checker passes it?

The problem is that you picked a Type 7 PID - which the legality checker considers to be "Very Rare GBA". So the fact that the Scyther is from HGSS gives it away as a fake. Is it OK to fudge the IVs a little to get the nature you want?

Heh, shows how clueless I am about this whole thing... I checked and apparently PID doesn't need to match IVs if the Pokémon is hatched. So basically all you need to do open Pokésav, enter in the new Trainer ID and Secret ID, click Generate next to the PID field, set the shiny checkmark and nature and stuff, and generate a PID. The PID will be different from that of the original Pokémon, but everything in-game should appear the same. Good luck!

The way I understand it, it's not possible to just change Trainer ID/Secret ID and maintain shininess, unless you luck out (basically on the order of rolling "another" shiny). However, depending on where you draw the line for it being the "same" Beldum from an emotional attachment point of view, we may still have some options - by changing the PID we may be able to change Beldum's trainer IDs while keeping its shininess, IVs and Nature (and we can certainly do so if the IVs are allowed to drift a bit). Here's what you do: Grab your new trainer ID and secret ID, and make note of the IVs and Nature of your Pokémon. Download the PID <--> IV generator and run it. When you get to the menu, choose option #3 and enter in all the data you wish to keep - the IVs, nature, and Trainer ID numbers. If it spits out a PID, you're done - there's a match for your new identity, and you can plug the given PID into Pokesav. If Step 3 didn't work, try menu option #2, and enter IVs slightly lower than the ones you recorded - it'll give you a list of possible PIDs and IV spreads to choose from. If you don't want to go through this, or if you couldn't find a good match to your original Beldum, there's one other possible solution: using Pokesav to change your own trainer ID and Secret ID to match your Diamond game. If you want to go this route, you can use Pokesav's "PID/IV" button to migrate your already-caught HG team over to the new trainer ID - they won't be shiny, but they probably weren't shiny to begin with, so it should be OK.
