Sometime in-between version 1.9 and 2.0 of Touhou Mystia's Izakaya, it seems as though the devs have either upped or changed the encryption of the unity assets.
There was a previous thread regarding this game, where the game was simply xored with one byte and was decrypted with a simple bms script.
When I tried using that bms script on the most recent version of the game, AssetStudio couldn't read it at all (no luck with just trying the files with no decrypting either)
Can someone help me what's different about the new version of the game? (these files are from version 2.1.3c to be specific)

Nothing has changed since that topic, encryption is still exactly the same, judging by the sample. I guess they've changed something in the bundle format itself. Also, there is no need to create multiple topics for the same game and question.

Hm... I see. If that's the case, would there be other solutions to this, such as alternate programs?

(also sorry about the new topic, I was unsure on how this website handled necroposting)
