both the Steam and Switch version have artifacting on all sprites contained in the "sactx" atlas sheets
meaning colours are blended and muddy, and not as clean and palette-friendly as they ought to be
The Switch version also 'swizzles' most of its textures -- use the TilED maps to unswizzle them




uses same method as Double Dragon Gaiden, canvas sizes and coordintes stored in "Sprite/" directory's JSON files under "m_Rect", and textures need vertically flipped to align with that data

sprites are bunched muuuuch closer than DDG, so I had to manually crop out stray chunks at the edge of every extract.

since a lot of sprites are sourced in the "sactx" atlases, you'll probably want to sort them by "m_PathID" so you know which file correlates to which sheet, this Python script will do that



import os
import json
import shutil

source_directory = "Sprite2"  # Replace with your actual path

def process_json_files(directory):
    for filename in os.listdir(directory):
        if filename.endswith(".json"):
            filepath = os.path.join(directory, filename)
            try:
                with open(filepath, 'r', encoding='utf-8') as file:
                    data = json.load(file)
                rd = data.get("m_RD", {})
                texture = rd.get("m_Texture", {})

                if (
                    isinstance(texture, dict)
                    and texture.get("m_Collection") == "resources.assets"
                    and isinstance(texture.get("m_PathID"), int)
                    and texture["m_PathID"] > 0
                ):
                    path_id = texture["m_PathID"]
                    target_dir = os.path.join(directory, str(path_id))
                    os.makedirs(target_dir, exist_ok=True)
                    shutil.move(filepath, os.path.join(target_dir, filename))
                    print(f"Moved {filename} to folder {path_id}")
            except (json.JSONDecodeError, IOError, PermissionError) as e:
                print(f"Failed to process {filename}: {e}")
