Okay, I'll need to be walked through this. I've done that and downloaded the files, what now? If I open the game will they just be there?
Ok, first, if you have any saves of your own at this time that you wish to backup, go to the game folder and move the GKSG.001, GKSG.002, etc, and the GKSG.cat file to some other place on your pc. Make a folder somewhere and cut/paste all of them to that folder.
Next, download all 3 zip files from Lafar's post #1, unzip them and place all the GKSG.001, GKSG.002, etc, (all 19 of them) in your game folder.
Lastly, place the GKSG.CAT file you downloaded (and renamed) from Lafar's other post also in the game folder.
And that's pretty much it, if all worked out you should see all 19 savegames inside your game
