深蓝貌似更改了加密方式，我解密失败，然后我用ds改了一下

用这个可以解

现在好像并没有进行加密，而是往文件头加了两个字节的的内容（0x7c），我尝试了该版本，但是发现了冗余代码，或许可以试试这个。（仅供个人学习研究使用，侵权请联系删除）

import os
os.makedirs("bundles-extracted", exist_ok=True)
for file in os.listdir("bundles"):
    path = "bundles\\" + file
    if not os.path.isfile(path):
        continue
    print(file)
    data = open(path, "rb").read()
    pos = data.find(b"UnityFS")
    if pos == -1:
        print("找不到UnityFS")
        continue
    open("bundles-extracted\\" + file, "wb").write(data[pos:])
