Can anyone help me with these sprites from the game Oreowa? They seem to use a sprite atlas but I have no idea how to turn the bytes into an actual file (I kind of forgot how I converted the integers to a file, and I also want the method of how it was done out there)oreowa.zip

this is what I get converting the integers in the .json file to hex

by the way, the .json was initially a monobehavior just to clarify

it's not really a spine .atlas or anything I actually recognize, idk what this is

also some source code from the game, might be useful
from Assembly-CSharp.dll\OREOWAOreowaUguiFlowChartItem.cs

public void Init(AdvEngine engine, AdvFlowData data, SpriteAtlas spriteAtlas, int groupNumber)
{
//IL_006d: Unknown result type (might be due to invalid IL or missing references)
this.engine = engine;
atlas = spriteAtlas;
gourpNumber = groupNumber;
Data = data;
sceneObject.SetActive(false);
imageObject.SetActive(false);
selectionObject.SetActive(false);
selectionItemObject.SetActive(false);
selectionItem3LObject.SetActive(false);
buttonObject = null;
buttonActiveObject = null;
((Component)this).transform.localPosition = Vector3.zero;
for (int i = 1; i <= 7; i++)
{
GameObject gameObject = ((Component)selectionObject.transform.Find($"Active{i}")).gameObject;
gameObject.SetActive(false);
}
switch (data.Type)
{
case "Scene":
InitScene();
break;
case "Image":
case "Line":
InitImage();
break;
case "SelectionStart":
InitSelection(isStart: true);
break;
case "SelectionEnd":
InitSelection(isStart: false);
break;
case "SelectionItem":
InitSelectionItem();
break;
}
IsRead = this.engine.SystemSaveData.ReadData.CheckReadLabel(data.FlowPoint.Replace("*", string.Empty));
((Component)this).gameObject.SetActive(true);
if (!IsRead)
{
((Component)this).gameObject.SetActive(false);
}
}

private void InitImage()
{
//IL_0063: Unknown result type (might be due to invalid IL or missing references)
imageObject.SetActive(true);
Sprite sprite = atlas.GetSprite(Data.File);
Image component = imageObject.GetComponent<Image>();
component.sprite = sprite;
((Graphic)component).SetNativeSize();
imageObject.transform.localPosition = new Vector3(Data.X, Data.Y * -1f);
}

The game uses UTAGE4's texture dicing converter

Can be reassembled using the script below

I did not make the script, but I did modify it to take arguments

dicing.py
