Hi, I hope this is the right place. I'm trying to extract audio and video files from the game "HoneyWorks Premium Live", but I'm currently missing the right key. I was wondering if someone here could help me with that?

The APK along with some cpk files (two audio and one presumably video) from the game, are in this drive folder: https://drive.google.com/drive/folders/1x-QdE1gHg6zDR0ZubKUHb1sU4Q5tS_Au?usp=sharing

Genshin Impact?
VGMToolBox will extract the USM and the audio files play fine (4x .hca files), but my issue is the video, which is an unplayable .m2v, likely meaning it's encrypted.
I'm not savvy enough with hex to understand what "larger than 0x140" and "repeating 0x20" means, so could you please assist?
Readme explains how to decrypt audio, which is not your case.
You need to find the video key. Key is usually inside some Unity script (depends on game), or in the global-metadata.dat file.
Try loading Unity files with AssetStudio and looking for monobehaviors named Cri(something) then extracting as raw, and looking at the context with a hex editor. Keys is a regular number in plain text.

is there any new version of that one USM demuxer lying around?

oh, new version was there two pages ago. grabbed it, saved it to an external drive, extracted it to a folder, then executed crid_mod to demux the usm file i wanted. fair enough.
what isn't "fair enough" is that, for video demuxing, crid_mod produces an m2v file that cannot be played on mpv, ffplay, or really any video player out there that can handle m2v files.
