Currently Sandboxing: Another Song Guide (Ported ver.)

In Project Diva Mega Mix+, Change Vocals (ボーカルチェンジ, lit. bokaru chenji) is a system that allows players to select different vocalists for a song that supports the feature. This changes the in-game vocal track to an alternate version, allowing for players to fully immerse themselves for more than just the original vocalist. Informally, this feature is often referred to by players as Cover Songs or Alternative Vocals, the latter being the official term used by SEGA for Project Sekai.

When a Change Vocal is selected, the game also automatically updates the performing character model on-screen to match the new vocalist. This includes changes to the character's presence in the PV (pre-rendered or scripted real-time performance), as well as their default module (costume), unless manually overridden by the player. Some songs even feature subtle animation or camera differences depending on the vocalist, such as the bulletin board at the end of Piano x Forte x Scandal.

For this guide, we'll be going through the process of adding a new audio track (henceforth referred to as the cover audio) to the Change Vocals system, using a pre-mixed version of a song (i.e. an album release). While those who wish to only change the vocal track itself are able to follow along, do understand that there will be some pointers in this guide where it will not work for your use case.

Requirements

Programs

• Audacity
  • This guide uses Audacity 3.2.5 (2023) for all screenshots
  • An equivalent or better audio editor (i.e. FL Studio) is also permissible. Please modify the steps to fit your editor.
• Notepad++
  • Any text editor can be used, however do understand that there will be some steps where manual intervention may instead be required.

Files

You should be starting with the following files:

• Your cover audio
• The original audio*
• The correct pv_db* file
  • Base Game: pv_db
  • Extra Songs DLC: mdata_pv_db
  • Modded Songs: mod_pv_db

If you don't know where to locate files with * next to them, please check Locating Files to find the appropriate file.

Tutorial

For this tutorial, I'll be using the Miku version of Kokoro from the album [Vocalo Tears]] as the visual guide.

Preparing the Mod Folder (WIP) =

C:\...\common\Hatsune Miku Project DIVA Mega Mix Plus\mods\
│─ My New Cover Mod\
│   │  config.toml
│   │  
│   └─ rom\
│      │  mod_pv_db.txt
│      │  mod_pv_field.txt  (Only if applicable!!!!)
│      │  
│      └─ sound\
│           └─ song\
│                │  pv_XXX_name.ogg

Checklist (WIP)

This is for users who have already know what they are doing, and just need a checklist to ensure they didn't skip anything.

• Cover Audio is aligned with Original Audio
• Cover Audio is named pv_XXX_[name].ogg
• mod_pv_db includes:
  • Original song entry
  • another_song or ex_song lines

Final Reminders

• Make sure your final mod_pv_db file contains only the song you are adding a cover to.
• If you are modding a song that uses *_pv_field (i.e. CoolChar's Project Diva X Songs Pack), make sure you include mod_pv_field in your folder.
  • This is due to some weird behavior with how SEGA handles loading these files, NOT a DML-caused issue.
• Covers will not:
  • Stack between different Cover Mod Packs that modify the same song
  • Stack with Lyric Translation Packs
• Be mindful of mod requirements, and note them in mod listings.
  • Not specifying requirements can lead to PVs calling the wrong files, or ghost song entries, which are songs that appear in the the game cannot load because the rest of the song’s files cannot be found!
