Thank you to @BLACKBIRD for contributing the Korean Spring League Shiny Poipole. It is added to our github gallery, and @theSLAYER will probably upload it fairly quickly to the site.
I gave up on GTS Daisuki Pokemon. It is damn near impossible to legality check. The ones I have are very different from each other with respect to trash bytes, PID, IV, and SID. So who knows if they are legal.
PreGen VI, there was no concept of region. Everything was language locked. Hence worlds in Gen 5 had wondercards for each language.
All serial code events are specific to a Console Region. There is an exception to this too. I won't go into details on it though. Just know that technically/legally any region and any language can redeem any event Pokemon.
