What file type are the save files? Most of the time I use notepad++ to make changes.
Link
Format "sr3s_pc". I tried open it with notepad++, but it shows me only symbols. Maybe i should change Encoding type? But i remembered, that i change it and it's not working. Could i attach file with my savegame here, for you to looking at it? Or should i upload it for some filehosting and give you the link in PM?
