Alright, so I checked them myself before putting them on the hack list. I still don't understand how Encounter Type PID Mismatch is shown on PKHeX (but I do have an idea)
08232 KOR Year of the Dragon Druddigon is fine with that error. Mine also shows the mismatch error. I don't really know what to do with the TRU Shaymin lol, since it definitely isn't supposed to show that error, but I didn't see anything wrong with it. Most likely hacked.
I put the Manaphy, Diancie, and Hoopa on my hack list.
Shiny Shaymin and Shiny Deoxys hacked.
Shiny WISHMKR Jirachi... Well, this is a problem. We talked in the hack checking thread about how gen 3 events are generally not supposed to have a fateful encounter flag. Well, there is one way it can have a fateful encounter flag: if it was improperly Pal Parked. This Bashful Shiny WISHMKR Jirachi is the same exact legit one hosted on Project Pokemon, except this one has a FE flag and theirs doesn't. Which could mean that either, it was edited later to have a fateful encounter flag, or (more likely) someone has a gen 3 .gpk file of the Jirachi and used PokeStock to Pal Park it. This one's legitimacy is up to you. It's the exact same legit Jirachi that's out there, but it has a fateful encounter flag.
