You need Python Blowfish, Ethteck's CC Decryption Tool, JPEXS Free Flash Decompiler, and a copy of Adobe Animate.

First thing, make sure you download Python to your computer. You can do it by downloading it in the Microsoft Store.

Then download Python Blowfish: https://pypi.org/project/blowfish/

Ethteck's CC Decryption Tool: https://github.com/ethteck/castlecrashers

JPEXS Free Flash Decompiler: https://github.com/jindrapetrik/jpexs-decompiler

Adobe Animate (you can pirate it)

After completing that step, create a folder and feel free to name it as you wish. I named it "Castle Crashers tool." Now after downloading Blowfish, find decrypt_asset.py and blowfish.py and put them in that folder. Now inside of that folder, create 3 folders.

One of the folders will hold the pak files name that folder paks, you drag your "pak" files inside of Castle Crashers to that folder you made. You can name it anything I call the pak folders "paks" just for simplicity. Now make a different folder inside of your "Castle Crashers tool" folder now make a folder named "unpacked" then create a new folder named "base" inside of "unpacked" folder.

Now go to your folder, the Castle Crashers tool folder, and then write cmd in the path dictionary bar, which, if you don't know, is that bar that tells you where you are in a folder, C:\Users\Desktop\castle crash tool … etc. After you write "cmd," the "cmd.exe" should start.

Write:
python decrypt_asset.py paks/(the pak you choose mine is player.pak) unpacked/base

After that, the unpacked folder should be filled with 2 files delete the raw file you don't need it.

Now open the SWF Decompiler. Put your swf file from unpacked to SWF Decompiler

in Right side your folder name should appear click on + then pick a folder below

Then pick a picture that you need and "export resource" as .fla file.

After that open Adobe Animate open the fla file then choose the entire pic then left click choose break apart then use convert to symbol and after that under graphics it should say symbol 1 left click export png sequence pick max resolution and thats it.
