It appears another "gigaleak" has gone down, involving Nintendo. According to sources online, it appears that Game Freak has been hacked, resulting in internal data from the company being leaked to the public. Those involved in the hacking community or those within general Pokemon related groups...
They can't use this code at all, it would be a surefire way to get the project shut down. Reverse engineering is the only way to operate something like that legally.
No romhacker or homebrew developer worth their salt will touch any of this. Using leaked material is legally significantly more dangerous than REing. I look forward to seeing the TCRF pages, though.
