DOWNLOAD PART2!: Now listen to tracks from Shenmue while you're exploring the different locations. Also includes the full Music Pack Mod adding tracks from Yakuza 1, 2 and 3 into the game.
This will affect the main menu, in-game dialogue scenarios, free roaming and boss fights. I think it spices up the game in very interesting ways.
I would have pushed things further and attempted a complete conversion but honestly Yakuza 0 is a headache to toy around with. Much of the actual music in cutscenes is tied to the voiced lines so... changing the music means no more voices. Hopefully someone takes my idea and expands upon it.
This is a very early work in progress that has not been tested fully and it may very well never be finished but at the very least you have something to enjoy if you are a fan of the older Yakuza titles.
Instructions: Drop the bgm.cpk file into the soundcpk folder within your game directory's media folder.
