Steps:
-Open Charles.
-Enter CityVille (play now)
-Make sure you can see both CityVille and Charles on your monitor screen as the timing as to be FAST.
-Find the line "fb-client-0.cityville.zynga.com"
-Expand it, and expand flashservice/
-You should see some gateway.php.
-Collect your rent and money from the businesses. Coins and Stars will drop out.
-Notice your TOP RIGHT hand corner of the game. As you click on these coins and stars, there is a BONUS bar. The moment this bonus bar has the word "EXCELLENT", quickly right click any gateway.php and select Breakpoints.
-You will notice in the game you will get 30bonus coins. If done correctly, a breakpoint tab will now appear in Charles.
-Find for this amount "30" as shown in the image below.
-Change it to 500,000 or LESSER. Don't be too greedy as a huge value will not work.
-This definitely works so if 500,000 doesnt work for you, use a smaller value like 20,000.
-Click EXECUTE 2 times. Clear the breakpoint from the gateway.php
-Refresh CityVille and you should see your new coins.
