Version j16 compatible also with newest OXCE can be downloaded here: https://drive.google.com/open?id=17G8iCziVoCOmNsGMCZwJBwXJ4vYTdyOB
Its not compatible with newest OXCE. Common and standard folders differ in latest X-Piratez versus Extended-5.6.1. Since X-Piratez was always combed together with OXCE it ran correctly from its own Common and standard folders.
But currently the two downloadable archives are not unified and Extended-5.6.1-eb44d4df4-2019-08-11-win64 throws all kinds of PCK coordinate errors, like STR_Biodrome_Weapon Offset -2 etc... when I overwrite the Common and standard folders in X-Piratez with the ones from latest OXCE.
* Just tried copying XPiratez into C:\users... Documents\openxcom\mods
but OXCE throws the same BIGOBS PCK coordinate errors.
While latest XCOM-Files runs fine, because its unified with the latest OXCE.
The install video

covers easy WH 40K, which has a different folder from OXCE that runs in the install video without problems. But X-Piratez has its own same name
Common and standard folders in the same place as the OpenXcomEx.exe.
