# Data Mods and Omnimix
!!! info "This guide will cover how to mod your BEMANI game's data folder in a non-destructive way.<br>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.
<img src="/img/datamods/1.png">
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/mod_folder/`.
If you're confused, the following may help you understand what this means.
```
├─ data/
├─── graphic/
├─── info/
├─── movie/
├─── sound/
├─── etc...
├─ data_mods/
├─── mod_folder/
├───── 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/).
<img src="/img/datamods/4.png">
- Open the archive.
<img src="/img/datamods/5.png">
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.
<img src="/img/datamods/6.png">
- Copy the `ifs_hook.dll` file to your game's `modules` folder.
<img src="/img/datamods/7.png">
#### 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`
<img src="/img/datamods/8.png">
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!
