Street Fighter: Duel images

[Hollow]

So, this game's images have a .png extension but I'm not sure if they have been protected or if they are packed in some form.

Spine files (skel, atlas) and plist are not protected, so maybe images aren't either, either way it's beyond my skillset.

Can someone look into the .png files and see if they are packed in some way or protected?

Here's an entire archive, I think it corresponds to a single character.

Any luck?  I'm also facing the same issue.  I initially tried opening the images by using a program called 'Apk Image Extractor' but it doesn't pick up those encrypted images in the 'Assets' folder.  While googling, I may have found a possible solution: [Discussion] A guide to make models of battle cats using SMBX : battlecats (reddit.com)
[Discussion] Finally decrypted BC files with my own scripts!! : battlecats (reddit.com)

That procedure involves using a script to decypt png files.  Not sure if it will apply in this instance, but it's worth a shot I suppose.  In any case, hopefully somone here more experienced will assist soon.
