Hello TeaEffTeu
I'm having a little bit of a problem when trying to extract the files from the game Super Mecha Champions, another game from NetEase that uses .npk files .

Maybe the script doesn't support this game yet.

If it's of any help here is a sample file: https://mega.nz/file/46MT1I7L#M4ATkgCfrzIkjPEfLz7800uK3x-YSFUQkysmDu5628o
(there's 12 files in total named res and every single of them weighs over 900mb)

and also, the log of my bms when trying to extract the files.

Response from the author:

Unfortunately, Super Mecha Champions' archives contain an encrypted table of contents. I am experiencing difficulty determining the encryption method and key.

Hello TeaEffTeu
I want to inform you, it seems they updated the Identity V npk today
When extracting the files from ui, instead of giving .png, the files comes out as .com
While when extracting the files from chr giving a lot of .raw files, these previously are various animation extension
If you would like to download the exe, this is the pc version of Identity V https://adl.netease.com/d/g/id5/c/gbpc
Or if you prefer the npk files, I can also send them

Response from the author:

Unfortunately, many assets have changed formats. Most PNG assets have been converted to a new unidentified format. The format must be identified before the assets are viewable again, but I'm unfamiliar with image formats.

EDIT: Please use NXRE to export UI assets as viewable DDS files.
