The purpose of this patch is to restore the licensed music from the Japanese version of Yakuza 3 that was unfortunately cut from all western versions of the game due to SEGA refusing to license the songs in question - "Loser", "Omoi Ga Afuretara" and "Jikan yo Tomare" by Japanese singer "Eikichi Yazawa" as well as "Don Quixote Theme" of the Japanese discount chain store "Don Quijote Co., Ltd.".
Additionally, all pre-rendered videos have been replaced by the original ones from PS3 as they are higher quality than their PS4/PC counterparts, you can find a comparison between them in the Images section, you will notice that the PS4/PC ones suffer from severe video macroblocking and artifacting issues which is why for this patch we opted to replace the videos with the PS3 ones.
Certain line of dialogue in a cutscene before the final boss has been corrected to feature a more accurate translation.
Finally, the Tamashiro Family Crest and Pin have been uncensored to the the original Rising Sun motif found in the original PS3 release that was unfortunately censored in PS4/PC versions due to its association with Japanese Imperialism in some regions of the world.

Those of you that might be familiar with our music restoration patches for the PS3 and PS4 Yakuza titles should be right at home with this patch.
This video below will give you a glimpse of what you can expect after restoring the licensed music - only intro shown as other places are spoilers:
