Introduction

This guide is a general how-to and reference page for modding UNICLR & MBTL characters. There are no official reference documents so everything here is determined by reverse-engineering / trial-and-error.

Assumed Knowledge

• Basic understanding of navigating File Explorer
• Basic understanding of batch files
• Basic understanding of programming

Note that French Bread uses Squirrel for most functions, but such code can be easily understood if you have JS, LUA, C and etc. experience.

Tools & Other Guides

Basic Tools

• Hantei-chan, a HA6 editor (linked is DamienIsPoggers' version with jonbin)
• CGlib, .cg extractor by u4ick
• CGTool, .cg compiler by u4ick
• A basic text editor such as Notepad++. Regular Notepad is fine but may be harder to use.

• A hex editor. HxD is used commonly.
• .pat editor / visualizer. None are public, but you can use HA6 + hex editor as a close enough replacement.

Setting Up The Modding Environment

Game files are located in a place like ...SteamLibrary/steamapps/common/UNDER NIGHT In-Birth Exe Late[st], or ...SteamLibrary/steamapps/common/MELTY BLOOD TYPE LUMINA This is commonly referred to as the game's directory or root folder. (REMEMBER THIS!)

Follow this guide for extracting MBTL files.

For UNICLR, simply download UNIST Unpacker, head to the /d folder in the game's directory, place UNIST unpacker there, and drag every file onto the unpacker.exe.Once you're done extracting, the unpacked / out folder's contents can be dragged to the root folder. Install the injector / _English patch file and now the game's code will read files from the unpacked folders instead of the archives. Editing the new folders will create changes in the game respectively.
