It's a free hex editor, a tool for programmers. Unzip and place it anywhere. No installation required. I place it in a folder I created called "Hex Editor".
2. Start CotD, launch the scenario you wish to customize, then save it.
3. Go to your save folder. Example: C:\Program Files (x86)\<Game location>\SavedGames, drag and drop the save file on to "HxD.exe" and the editor will open it up.
See attached picture:
Highlighted is the location for start date. "0A" in hexdecimal is "10" in human speak, and "09" is "09". The start date in "Early Russian Arrival" is 10-9 or October 9. This isn't correct. Change it to October 2 by typing in "0A 02". I even run it for a few turns to see if Augereau would show up on October 8. He did. In the old setting he would never show up, being past his due date.
So far I have only found the start date location. Next I need to find the indicator for city ownership, which is probably in 0/1 switch.
Just a small tip. In the hexdecimal system, number goes like this:
01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 (10 in machine speak is our 16)
11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 (which is really "32")
Windows calculator can do the conversion for you. Click "view" then select "Programmer".
