Senran Kagura Burst .bin archive compression

[Spy Ring]

Hello, I have a problem with certain archives of the game Senran Kagura Burst.
Important archives of this game are compressed and i don't know the compression.

Please help me for decompress archives.

I guess it's a compression not supported by quickbms.
The first 32bit is probably the decompressed size, followed by a 32bit zero and then the raw compressed data.

Probably a custom RLE compression in Little endian.
It's similar but is not a RLE compressed file.
This compression may be created by Tamsoft or MarvelousAQL, I don't know.
