A Battle Video was released to promote Zeraora, and various hackers went to dump the Battle Video, in order to extract the Zeraora.
What is interesting, is that this file has the same details the Japanese distribution.
The other Pokemon from the Battle Video was also added to this page.
They've been leveled to Lv.100, as their level was meant to be 100, evident by the fact that they were hyper trained.
Additionally, the Battle Video has also been added to this page!
It goes into the extdata 00001B50\user\btvideo and can then be watched from the Battle Video menu.
While this file won't make your save illegal, we don't recommend using it.
