Havent read to see if it is posted and I honestly don't want to spend the time. :P
Anyways new zoom addy is 0056c8dc
Speed dunno yet. Not making a program becuase others are better at it just use cheat engine until they do or if they did.
Download cheat engine. Just google it
Open it and at the mid right should be a button called 'add addy manually'
do that put in the memory addy from above.
you can save it as a file after that in the menus on the top left so you can open it again without adding the memory addy.
then select program in top left button and find conquer.exe it will likely say 256 value after that
you can change the value down to 150 in there or whatever you prefer.
Also its the easiest way to find the zoom addy when it changes as you use the base search '256' then zoom closer and search for anything changed to a higher value then change back to normal view and final search it as 256. maybe 4 will pop up just poke them until you find the right one. :P
