Hi guys,

today im moving my interest to a new ios game that i am looking to gain a better understanding of in terms of game files, i come from order and chaos online in which used a form of pk header to properly convert the game files into zips without damaging them and then extracting them,

Crusaders of light however, uses .npk files with nxpk headers inside the files themselves which i cannot manage to figure out how to properly rename and extract

thanks for any help!

Not seeming to have any luck opening the file using 010 and the script you have given me.

error is as follows:

*ERROR Line 11: Unknown pre-processor directive 'NXPK'.

Hi ~ aluigi.
I use BMS script to extract these files, work progress of 199%, close to the perfect, but there is a problem, part of the DDS picture is damaged, what is the reason? :P

As far as I can see the format doesn't use chunks and the compression algorithms involved report errors if there is something wrong.
Additionally nobody reported problems with the files coming from the nxpk archives.
The percentage over 100% is normal with some archives that use lot of MEMORY_FILE operations like these ones.

Just checking the dds image with a hex editor and I don't see garbage data or corrupted fields so I guess it's ok.
Maybe is it something related to the DX10 support of your viewer?
Graphics is not my field, sorry.

@alugi I am also trying to extract assets from this mobile MMO

I am using QuickBMS + NXPK script to attempt to extract UI assets from a file labeled 'uires.npk'

QuickBMS is able to unpack the assets. However, many appear to be damaged/corrupted and have visual anomalies. Here's an example:

There's also a lot of .png images which appear to be an image mask?

Image

I know that people have successfully dumped the image assets in this game as PNG format. Here's an example of how the image should appear:

What method should I use to properly extract these images?

i think you already succeed. the black-white image is an alpha mask, with tools like ImageMagick you can get the third pic from the former ones.

Thanks @festergut I was curious to know if there was a step I was missing, do you recommend imagemagick only because it's free or does it do some "smart" autonomous stuff that photoshop will not do without configuration?

Thanks

imagemagick may not be the best choice, but i am not good at photoshop, not knowing how to accomplish that. perhaps it also works.
