Hello and welcome to this guide showing you how to mod the Mega Man Zero/ZX Legacy Collection. This guide will show you how to create music mods and add mods into the game, alright let's get started!

Introduction
MZZXLC Mod Loader is a basic mod loader for the PC version of Mega Man Zero/ZX Legacy Collection. This loader is meant to allow existing mods for Fluffy Manager 5000 to be used as well as code-modifying mods.

Instructions
1. Navigate to the game's folder by right-clicking on Mega Man Zero/ZX Legacy Collection in Steam and clicking on Manage -> Browse Local Files

2. Copy MZZXLC_mod_loader.asi and d3d9.dll to the game's folder.

3. Run MZZXLC.exe, this will create a mods folder.

4. Copy mods into the mods folder and start the game.

This loader is meant to be compatible with existing asset-swapping mods for Fluffy Manager 5000. Mods meant for this mod manager can be copied to the mods folder and will show up in the mod list.

Note: Instructions have been carried over from the Github page written by Greiga Master, even further instructions for modders and what not can be found there.

In this section I'll be going over how to mod music into the Mega Man Zero/ZX Legacy Collection. For starters make sure to browse the game files and the BGM files to mod are located in "./nativePCx64/sound/bgm/wav/".

In this folder you'll see eight folders the contents of the folders will be listed below:

"zero1_bgm" = Mega Man Zero
"zero2_bgm" = Mega Man Zero 2
"zero3_bgm" = Mega Man Zero 3
"zero4_bgm" = Mega Man Zero 4
"zx_bgm" = Mega Man ZX
"zx_ad_bgm" = Mega Man ZX Advent
"zero_com_bgm" = Mega Man Zero Collection (I don't think these are used in the game at all.)
"new_com" = Mega Man Zero/ZX Legacy Collection

If you want to make your own music to put into the game you can do so by converting a file to an OGG file at 48kHz. I used Audacity to convert tracks and just to be sure made duplicates of each track and saved each track under which track I was trying to replace to ensure the sound file worked with the collection. When setting up loops in Audacity you need to make sure to have the timecode set to samples as the "LoopStart" and "LoopEnd" tags use it

When saving files in Audacity make sure to have three different tags:

Looping Files
LoopStart: ###
LoopEnd: ###
Ver: 0002

Non-Looping Files
LoopStart: -1
LoopEnd: -1
Ver: 0002

### represents the sample number which can be any number of digits. The "Ver" tag always has to be set to 0002 or it won't play in the game.

For further help you can check out a video tutorial here:

The tracklists for each game will be listed in each section below.
