Introduction
This section will show you how to set up Mega Man X Legacy Collection in Fluffy Manager 5000. Fluffy Manager 5000 allows an easier means of installing and uninstalling mods, swapping mods, etc. Fluffy Manager 5000 also backups the original files just in case a mod you've installed or making is having issues. For starters you'll want to download Fluffy Manager 5000 here: https://www.fluffyquack.com/modding/

Note: If you just want to install the mod packs the classic way you still can just copy the "nativeDX10" in your Mega Man X Legacy Collection root directory without the "modinfo.txt" or "screenshot.jpg" files.

Step 1
Once you've got Fluffy Manager 5000 installed somewhere fairly convenient you'll want to open it up.

Step 2
Click "Options" and once in options click "Define game info"

Step 3
Click "Current game" which should be the top option, once clicking that you'll see a list of games and you'll want to select one of the "Custom Game" options.

Step 4
Click "Game name" and type in "Mega Man X Legacy Collection".

Step 5
Click "Mod directory" and type in whatever you want to call the directory and Fluffy Manager 5000 will create it for you I personally just put in "MMXLC"

Step 6
Click "Executable name" and type "RXC1.exe"

Step 7
Click "Steam ID" and the Steam ID for this game is "743890"

Step 8
If it hasn't been filled out yet you'll want to click "Steam Directory" and type "Mega Man X Legacy Collection".

Conclusion
After that you can go and put in mods in the mod directory Fluffy Manager 5000 made for you and then refresh the mod list and you should be good. Also make sure that the mods folders you put in have a "modinfo.txt" file in their root directory.

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

Note: The video guide provided is for the Mega Man Zero/ZX Legacy Collection, but I do plan on doing a more in general video for this and the other collections. That said, most of these instructions should work as long as you just apply it to the Mega Man X Legacy Collection.

In this section I'll be going over how to mod music into Mega Man X4... since Mega Man X1-3 are emulated. For starters make sure to browse the game files and the BGM files to mod are located in "./nativeDX10/X4/sound/bgm/wav/".

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

"bg" = General BGM
"boss" = Boss Introductions
"clear" = Title Themes / Stage Clear

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.

Note: This guide is for the Mega Man Zero/ZX Legacy Collection, but it ultimately works the same for Mega Man X4. A more general guide will be made at a later date.
