I have been trying to decrypt these archives with no luck and was hoping if anyone here would able able to help.
I've found what seems to be the decryption key in the eboot at offset 0x806f78 since editing this string using ProDG debugger causes encrypted assets not to load

Code:

86F958D4-46A8-4F31-A90F-74A7F23609ED

but so far not been able to gt anything using it.
Here's some sample file https://mega.nz/#!h8JwnJKI!Ld8V8rebnlzqIHmwRRSv_ZUSokF2xrKl2pyCWBlUlW8

The link you provided doesn't exist.
There is also no name of the game specified in your post.

This game is Idolmaster One for all.
There is a decryption tool here
https://github.com/faraplay/ImasArchive ... bishBox.cs

Looks like is the file name this string as a blowfish key?

Can this be done in quickbms?
