+# Data Mods and Omnimix
+
+!!! info "This guide will cover how to mod your BEMANI game's data folder in a non-destructive way.
No files will be removed or overwritten."
+
+---
+### Pre-requisites
+
+!!! tip ""
+
+ - A fully working and unmodified game.
+ - The data to mod your game with.
+
+!!! danger "ATTENTION"
+
+ - Please make sure the mod you're installing is **compatible with YOUR specific game and game version**.
+ - If connecting to an **online network**, make sure they **explicitly allow** the mod you're about to install.
+ - TWO-TORIAL will **NOT** provide support with issues caused by mods besides **Omnimix** for beatmania IIDX.
+
+---
+### Preparing data_mods
+
+!!! tip ""
+
+ Let's place your mod files in the right folder.
+
+ - Create a `data_mods` folder next to the others in your game files.
+
+ 
+
+ Depending on how your mod is packaged, you may or may not need to create another folder to contain it.
+ Inside that folder, the structure should follow the one in `data/`.
+
+ - Place your files inside that `data_mods/folder/`.
+
+ If you're confused, the following may help you understand what this means.
+
+ ```
+ ├─ data/
+ ├─── graphic/
+ ├─── info/
+ ├─── movie/
+ ├─── sound/
+ ├─── etc...
+ ├─ data_mods/
+ ├─── folder_name/
+ ├───── graphic/ <- files that mod the /data/graphic/ folder go here
+ ├───── info/ <- files that mod the /data/info/ folder go here
+ ├───── movie/ <- files that mod the /data/movie/ folder go here
+ ├───── sound/ <- files that mod the /data/sound/ folder go here
+ ├───── etc...
+ ├─ dev/
+ ├─ modules/
+ ├─ prop/
+ ```
+
+!!! info "Example: Omnimix for beatmania IIDX 31 EPOLIS"
+
+ **Directory**: `contents/data_mods/`
+ 
+
+ **Directory**: `contents/data_mods/omnimix_31`
+ 
+
+---
+### Loading data_mods
+
+#### Installing ifs_layeredfs
+
+!!! tip ""
+
+ We now need a way for our game to load our mods.
+
+ - Download the most recent release of [ifs_layeredfs](https://github.com/mon/ifs_layeredfs/releases/).
+
+ 
+
+ - Open the archive.
+
+ 
+
+ What we're interested in are the `64bit` and `32bit` folders:
+
+ - Your game is 32bit *(spice.exe to launch)*: go in the `32bit` folder.
+ - Your game is 64bit *(spice64.exe to launch)*: go in the `64bit` folder.
+
+ 
+
+ - Copy the `ifs_hook.dll` file to your game's `modules` folder.
+
+ - Back to the archive, go inside the `automatic_injector_dlls` folder.
+
+ 
+
+ - Copy the `d3d9.dll` file to your game's `modules` folder.
+
+ 
+
+#### Loading ifs_layeredfs
+
+!!! tip ""
+
+ All that should be left to do is tell spice2x to load `ifs_hook.dll`.
+
+ - Open your game's `spicecfg.exe`.
+ - Head to the `options` tab.
+ - Find the `Inject DLL Hooks` option under `Common` and type in `ifs_hook.dll` then press Enter.
+
+ Note: If you have other DLL hooks, simply add more by having a space in between them..
+ Example: `ifs_hook.dll somehook.dll`
+
+ 
+
+ Assuming your `data_mods` folder has been made properly, that's it!
+
+!!! danger "Extra step for beatmania IIDX Omnimix"
+
+ You also need to patch your game's DLL with the `Omnimix` patch.
+
+ For more information on how to patch your game, head over to the [Spice2x Patching](../extras/patchsp2x.md) page!
