It's part of the custom rom.The root shouldn't make a difference with the Pokemon that I have seen.I have a son that plays it all the time still,and his is rooted.I would unzip the custom rom and see by chance if it's a part of an .apk file itself and see if installs and works.I don't own the device so I can't say for sure.I would read up on the custom rom on XDA Developers.That should put you in the right direction.
