The latest version of the converter from zip to orc and vice versa by mamaich: http://www.multiupload.com/AVYP2UAWXL

I've attached the recompiled version for the public closed beta in this message.
Oh, thank you! Thanks to this, I was able to open several new maps in the public closed beta 1.4.
I extracted the missing maps from demo 1.3 (in Data2.orc/Scenario), put them in Data10.orc/Scenario, and copied Data9.orc/Game Data/maps.xml to Data9.orc/Game Data/maps_beta.xml.
Archive with maps: http://188.242.31.139/maps_mmhvi.zip
I don't quite understand where to put the maps; I don't have any folders similar to Data (((
You need to use orc2zip to create regular archives and then put the necessary files in them, and then use zip2orc to create orc files.
For those who don't want to bother, here is the modified Data10.orc with new maps for the public closed beta 1.4: http://188.242.31.139/Data10.orc. You don't need to change Data9.orc; everything you need is already in Data10 (:
