## Modding Tools

### OMORI

Having OMORI is a given, but in case you forgot you can get it [here](https://store.steampowered.com/app/1150690/OMORI/).

### Oneloader

Get Oneloader, the mod loader [here](https://github.com/rphsoftware/OneLoader/releases). **This is required to create and install mods.** Learn how to install here.

### Bundletool

[Bundletool](https://mods.one/mod/bt) allows for the creation of mod zips for mods built off of a playtest folder. Created by Rph.

### Data Editing

Get RPGMAKER MV [here](https://store.steampowered.com/app/363890/RPG_Maker_MV/). **This is required to edit OMORI's data, map events, enemies, etc.** It's expensive but goes on sale often, you can see if it's on sale [here](https://isthereanydeal.com/game/rpgmakermv/info/).

### Map Editing

Get Tiled [here](https://www.mapeditor.org/2017/08/29/tiled-1-0-3-released.html). **This is required to edit OMORI's map sprites and tilesets.**

### Dialogue and Plugin Editing

While you can use just about any text editor to edit OMORI's dialogue and plugins, VSCode is recommended. It can be found [here](https://code.visualstudio.com/).

### Sprite Editing

Any digital art software will work for this. You can use [Medibang](https://medibangpaint.com/en/) for free for all purposes, but [Aseprite](https://www.aseprite.org/) is a good paid option for pixel sprites/tilesets.
