https://drive.google.com/drive/folders/1aUeBdEhdIc_tvkMl94gsfHLPHCNXUzPTI have the Steam version of Steel Fury and JSGME was installed before I installed STA. I followed these instructions from a poster in the steam discussion group.
1.Unzip the mod folder,
2.run jsgme.exe and disable all the your currently active mods in reverse order.
3.Remove all the mods from the MODS folders inside the STA3.4 folder and paste them to the actual Steel Fury 1942 game MODS directory, create a MODs directory if you don't have one. These mods are installed individually and in the order described below- the installation order is important
4.once you've moved all the mods, delete JSGME.exe and JSGME.ini files located in STA3.4 folder; you shouldn't need these files as JGSME should already be installed if you have the steam version.
5.move the STA3.4 folder itself into the actual Steel Fury 1942 game MODS directory
6.run JSGME.exe
7.disable compass mod and unofficial patch (these files are installed by default in the Steam version)
7,5.delete data\sound\loc_rus\speech directory (or copy elsewhere safe) note: I just renamed the folder and left it in place.
8.enable the mods in the following order polygons2.8, ssm2.7, STA 3.4 and you are done, now you can play.
9.to play you have expand the common section, select local server click 'start' (this window will pop up when you start the game, leave the language as 'non English ' or the game won't start}
10.enable other mods with JSGME if you wish to experiment what are they about (?) Note that the weather mods should be added and removed as you need them, pretty sure you can't just activate everything at once.
Note I'd already used the 4GB fix on the Steel Fury executables, whether this is needed for the STA mod I don't know. It works with it.
I still get the occasional scenario that won't load and in some scenarios there appears to be elements of the skins absent on some of the tanks, but other than that it is a brilliant piece of work.
One other point, newbie learning curve to a certain extent. My screen is 3440 x 1440. Although the resolution is supported you will need to manually edit the the aspect ratio in the engconfig file to 2.388888 or the playing screen will stretch the images on the screen.
Enjoy :-)
