Hey, I went through some of my old save files and found some untouched wonder cards so I extracted some of the missing Korean events. (Used pokegen to extract, hope the files are not messed up)
The zip file contains pcd for the following:
Characterfair Shaymin, Korean Crown Entei, Korean Crown Raikou (sorry apparantly I didn't go get Suicune...bleh), NOK Regigigas, Shinsegae Feebas, and Shinsegae Munchlax.
Hope that helps fill up some empty holes
edit: if the said pcd don't work PM me or something and I'll send you my save files
