Uses Kraken, after testing with KaktoR's Oodle library collection, v2.9.0 seems to yield the best results, however even with this library a considerable number of streams are dropped. Against the attached sample 88/231 steams are processed (full recompression currently, as reported by XTool, indicates 6248/7387 streams are processed), verbose output indicates streams are at a depth of L4.
xtool 0.7.8 (-mkraken:l4:n128:t256+zlib+reflate) + srep + lolz
It should be noted that it seems at least with the current library re-compression isn't very effective, with the reinflated output only being ~10MB larger than the initial input. The original Oodle DLL matches the CRC-32 checksum for library v2.6.0, when compared against KaktoR's kindly supplied checksums for all current library.
