Now select all addresses and press the button with the red arrow to copy them to the address list. This will allow you to modify them.
Next, select all addresses in the address list on the bottom, right-click on them and select
Change Record > Value, or simply press
Enter. Change the value to 1.
What you just did is you changed the purchase price of
HarvEstate Manor from 1,000,000 to 1 coin. Go ahead, buy it and place it on your farm. Now, go back to Cheat Engine, clear out the address list and search for 50000 by clicking on
New Scan and then
First Scan. Select all results and copy them to the address list. Once again, select all addresses in the list, right-click on them and select
Change Record > Value (or press
Enter) and change the value to 2000000. You can specify a greater value, however, FarmVille only allows up to 2,000,000 and will discard the rest. Once you've updated the value, go back to FarmVille and sell the
HarvEstate Manor you just bought for a nice 2M in coins.
