Kingdom Hearts Final Mix

Kingdom Hearts Final Mix is a Japan reissue of  that uses English voice acting with Japanese subtitles among additional in-game features. The PlayStation 2 version of it is exclusive to Japan.

The game was remastered in HD and released as part of Kingdom Hearts HD 1.5 ReMIX for PlayStation 3 on March 14, 2013. As opposed to the original Final Mix, the remake features Japanese voice acting in the Japanese release. As part of the collection, it was made available outside of Japan for the first time. It was later released on PlayStation 4 and Xbox One as part of Kingdom Hearts HD 1.5 + 2.5 ReMIX.

Development
Many features, plot points, and other miscellaneous elements initially had to be cut from the first Japanese release of Kingdom Hearts due to time constraints. Instead of simply dubbing the game that was made and shipping it internationally as is, the team decided to reintroduce some of this cut content in the international release. Realizing that Japan was left with an incomplete package compared to the rest of the world, the team decided to re-release the international version of the game in Japan. Even more cut content was reintroduced in this version, which the team finally considered feature complete, hence the Final Mix subtitle. Due to a significant amount of English voice lines being recorded for scenes that were not in the original Japanese version, the team elected to not redub the scenes and instead used Japanese subtitles over the English audio. New scenes either used recycled audio or had no dialogue at all.
