The game came out in December of 2018 in Japan, and mere 3 months after that in March of 2019, Pierre Taki was arrested for possession and use of cocaine. Originally, famous Japanese actor Pierre Taki portrayed Kyohei Hamura, who is a very important character in the game. To explain the reason for this patch existing you’ll need to understand the history of what happened with production of the game.
This is an unofficial patch for Judgment, or Judge Eyes as it’s known in Japan, meant to restore Kyohei Hamura’s original appearance and Japanese voice to the likeness of the actor that portrayed him in the original, launch version of Judge Eyes in Japan, Pierre Taki.
