Thanks for advice fitzcarraldo. It's exactly hard piece of work, but probably the only solution for preparing it to proper work.
This evening I'm really irritated trying to start SH3 and load saved campaign three times with no success - three CTDs
Now I wanna prepare the new mod soup with really must have mods, without WB's USAM, and check what will happen. Like others I have many mods, many of them conflicted, especially with sensors.cfg and sh3.sdl files. This was always big problem playing SH3 to merge all of them in proper way and avoid conflicts between them. It's crucial to do it in the appriopriate order.
