You will need: WPE PRO 0.9a
Most
virus scanners will detect virus in this program. I would say that it
is not an issue as this is not your normal memory scanning program. If
you're afraid of getting viruses, feel free to not use it.

FOLLOW THESE STEPS =D
CLOSE YOUR ANTI-VIRUS FIRST IF YOU ARE UNABLE TO OPEN WPE.

Step 1: Open WPE PRO, click on "Target Program" and select "Firefox.exe"
Step 2: Load the Roller Coaster Kingdom. When you are at this screen >>


Step
3: Let Roller Coaster Kingdom load finish. I usually give it about 2
minute after the game has completed loading before pressing the STOP
button. This ensures that I find the code for EXPERIENCE points.
200-300 packets should be found.

Step 4: Now search for the code
x":"Game","c":"a
wardDailyReward"
,"p":{"deltaMone
y":17,"offlineMu
lt":0.5,"numBuse
s":3,"parkOpenS
ecs":167,"numPe
eps":12},"r":-1}}. (i find that searching from bottom-up is easier)

Step 5: When you found the exact code, right click and select SEND
Step 6: Now edit these values
Example :

a. ":{"deltaMoney":17," --> ":{"deltaMoney":99,"
b. "numBuses":3," -- > "numBuses":9,"
c. "numPeeps":12} -- > ,"numPeeps":99}


Step 7: Now select the "Continuously" radio-box and click on the PLAY button beside the PORTaddress.

Watch as your gold increases. To increase it even more, change the 0.5 to 9.9.
