Another modification some players seek is an "Undub" version of the game. This process involves taking the Japanese audio files and inserting them into the European or American version of the game. The goal is to play with the original Japanese voice acting while retaining the translated English text. While directly related to modifying game files, not save files, it is a popular modification that may require using a corresponding save file to be fully compatible. The process involves extracting the ROM from both the local and Japanese versions and replacing the audio files—an advanced task that requires specific tools like Kuriimu.
