I've been investigating a 2017 title "Lone Echo", which seems to use a previously undocumented Oodle Library, v0.1.0, and whose CRCs don't match any other libraries, as posted by KaktoR.

Code:

    

File:   oodle_11_win64.dll

CRC-32: 15a0f169

Attempting to discern which member of the oodle family is used has proven to be a tad tricky, with each sample spitting back a result of [0] (Invalid/Unknown) as reported by Razor's Oodle Stream Scanner (oo2scan_7_win64.exe) utility. Attached is both a sample and the library in question. Since these streams are coming up as Invalid/Unknown is it not possible to re-compress them?

This oodle version is so old and might not be worth looking into, xtool supports v2.1.5+, anything older than that is considered ancient. An update in xtool might add support for this game but I don't plan on releasing anymore updates this year.

Information I gathered from the file:

Code:

Signature - 8 byte (0x53534552504D4F43)

Unpacked size - 8 bytes (70921828)

Packed size - 8 bytes (33767326)

repeated 256kb compressed oodle blocks

Code:

unpacked block size - 8 bytes

packed block size - 8 bytes

compressed block

Advanced configuration can be made from this information to collect the streams and that's needed is library that uses oodle_11_win64.dll for precompression.

For XTool, use this:

Code:

-mzstd:l3 -df5p -dd5

Used libzstd v1.3.0.
Use XTool v0.7.9.hotfix1 (others will get stuck/crash).

-- Edit --

I don't know if it makes any difference to use this totally not weird looking key, but nevertheless it got some additional streams.

Code:

Time: 00:29:10 (CPU 02:26:51)



Size: 16.2 GB >> 47.4 GB

oodle library 2.8.14 should be ok to use.

Maybe use zlib after that to get even more. In some cases if you precompress oodle streams, there are several zlib streams behind that aswell.
