Tried it on a file from Mass effect andromida.

ztools pzstd expanded it to 174.85%
xtools expanded it to 177.14%
ztool with v parameter 177.27%(since this produces result without varification, hence can b used for comparison. jusk like we use DS4Zlib before precompression.)

extraction is also successifully

After treating the output with srep + lzma

ztool 20.38%
xtool 20.21%

is it possible to provide v parameter with xtool, it might come handy for comparison.
