I see, here is the .apk file :!5Npn2YDD!DN3UXybCHf7lCgWTDFm0QsEok-IhKNWe_xfIsrE30qk

Oh, I already checked the .apk, as mentioned it's hard to find the key in this case. I'll try again later though.

Was just pointing out that having the .hca/awb alone isn't enough to do anything, so that people can stop uploading that.

An update on the game I asked about last Nov.

game:ブラックスター -Theater Starless-
apk file:!Plc3lS5R!qXbXHe8kK4uBdZshX3mW4JFSWOvoaWT3Phaxwx4DwKE

bnnm kindly helped me found the key but I failed to decode the hca files. Thought it was something wrong with the tools I used and left this behind.

I just found it today that the key bnnm gave me(0x0000001C5E0D3154) was used for criware movie files(usm). I used this key and decoded a movie file successfully.

Seems that this game uses different keys for audios and videos. Could someone check this please?

@random - added key for Detective Connan Runner in the latest vgmstream.

Also updated cri movie unpacked tool to handle multiple streams found in Dragalia Lost!TJQniYwL!Dp_D-KvzVlVgTwqzVJc1n3vslBZsHdy8pdDqzhRtsOI

@sandimy - all music works fine in vgmstream, but you must open the .acb instead of extracting the .hca.
Otherwise you'll need to manually create a key per song, since there is a sub-key in every .acb.

Hi guys, I'm trying to extract the video in a game called Uni's On Air. I tried for a few days, still haven't managed to find anything decent. Can you guys please help me to find the key?


The APK along with some cpk (usme files inside) files downloaded from the server:

Any help would be much appreciated. Thank you.

Key is 0000047561F95FCF, use the cri movie unpacker tool above to decrypt.

@bnnm Thanks! It works like a treat!

And may I ask how do you derive that key?

USM keys are often the same as HCA keys (not always), so I just tried that. The HCA key is the same as Shin Tennis no Ouji-sama: Rising Beat (same dev), plus in Unity games keys are often in plain text and easy to find. (also see here)

Hey guys, I was wondering if anyone is able to decrypt the HCAs for Touhou Gensou Mahjong for the Switch? Whenever I try to play the files, they either come out silent or glitched. I have a similar problem with Billion Road (also for Switch). Thanks in advance to anyone who can help!
