A mobile game that will soon shutdown.
Same company as Aura kingdom, but the format is very different (or compressed)

All files are stored in a folder called "nfs".
Some files have a header with the string LZMA, which seems to be different from the general LZMA format.

There is common hex data from 0x10 to 0x2F.
CC 4D 4D 2A AA CC 57 70 CB CC 49 55 70 CB 2F CA:

*There is a Windows version of this game, but the file is the same as the Mobile version.

*The same format is used in Aura Kingdom 2.

It's a 12 bytes header followed by the compressed data, zlib or LZMA signature with lzma data.
The header is encrypted and so it's not possible to know where the compressed data ends.
offzip can easily extract the zlib data.
LZMA is different since there is no termination mark.
