Future of modding | Data.win

With this guide, I want to start modding, the smallest and simplest - replacing sprites, sounds and fonts

Data.win

Going into the directory with the game, I noticed that there are no folders with sprites and other visual information for the game to work. However, here, in the folder, there is an archive - Data.win. This archive contains all the files for the visual of the game. The only thing that prevents us from viewing its contents is the format.
Let's omit the part of how I found the software I needed and proceed to the main part of the manual!

Right Soft | Undertale Mod Tool

Download the following program from GitHub - Undertale Mod Tool
( https://github.com/krzys-h/UndertaleModTool/releases )
Next, unpack the downloaded archive to the place we need, in my case, this is the desktop and open unpacked archive
Now run UndertaleModTool.exe

Work

This is the main window of this program. By the way, it is used not only for Undertale, but also for other games made in Game Maker Studio.
To start our work, open the archive we need
It is located in the following path - U:\Steam\steamapps\common\Synthetik
After selecting the desired file, we wait a little, after which such a window will appear, click ok
In the left section you can see tabs with corresponding names, they contain textures and sounds. Clicking on the tab drops out a menu with content. Select it and we can see the texture. Here you can change its name for the game, etc., but what is more interesting, you can replace any file with your own, or export it to the desired folder.
By the way, this software contains scripts to simplify work with such archives. For example, it is possible to export all sounds or textures at once.
By selecting the export of all textures, this operation will be performed. Everything exported will be placed in the root folder of the game. Truth will have to wait.

Sprite replacements

Select the desired texture for replacement and click on three points
Now click on - import
Next, select a picture to replace. It is important that the image is in the format PNG!
After the necessary changes, press CTRL+S
Now let's go into the game and check our changes
Not the best replacement, but the main thing is to show that it works.

Result

As we can see, with the help of this software, you can change the visual part of the game, and with knowledge you can achieve exquisite results, in the form of textpacks in a workshop. I really hope that this guide will help in the beginning of mod building this rougelike!
