Remember to upload files on good file hosters like google drive, mediafire, sendspace, mega or dropbox.

Try this script for decrypting the files and open them with an SQLite software:
Code:
encryption xor "\x7e\x19\x6c\x71\x79\x7d\x10\x2e\x7b\x1d\x1b\x12\x7e\x7c\x00\x3f\x65\x0b\x6e\x76\x75\x75\x7e\x2e\x00\x00\x00\x00\x7c\x7b\x0c\x37\x0b\x0b\x15\x6b\x6e\x67\x7c\x29\x0c\x08\x6e\x00\x07\x66\x17\x25\x09\x0c\x19\x63\x00\x67\x07\x34\x17\x1a\x6c\x07\x0b\x6e\x79\x25\x72\x11\x02\x71\x02\x60\x0b\x3c\x79\x1a\x17\x1a\x10\x7c\x7b\x22"
get SIZE asize
get NAME basename
string NAME + ".sqlite3"
log NAME 0 SIZE

Great! This can work,
However, I extracted the blob data in sqlite3, there are 2 kinds of files (fsi & fsb), it seems to use XOR encryption again?

This is newfiles download link

They are some custom containers/formats for textures in dds and jpeg format.

The FSB files start with the "GEPJ" magic + size + jpeg data + zlib compressed data (some sort of "mask"?).
You can extract the jpeg file with this script:
Code:
idstring "GEPJ"
get SIZE long
savepos OFFSET
get NAME basename
string NAME + ".jpg"
log NAME OFFSET SIZE

The FSI files start with an "ISF" magic but can't help further on them.

tks,Great!
Fsi file seems to be compressed using nvtt, this is nvtt

There is a decompression library here.
Is this useful?
