I'm trying to edit Saved Games so I can tweak the errors I make in OOBs as I go instead of having to replay them to change unit-types or fix terrain. I get the Saved Game file. Change the name to SPMBTscn.XXX and move the files to the Scenario folder. Nothing appears in the slot I designate with the new number, and if I click on the vacant line I always get a window pop open that says "Saved Game Failed To Load" This happens both in SPMBT and WinSPWW2. Is there a tweak for the near computer illiterate I'm missing?
