Since there are a lot of people wondering which hacks are working for Farmville and which are not, and nobody cares enough to read through 75+ pages of text (and I wouldn't expect anybody to), I've decided to make a new post with the updated hacks. I will update it whenever a new released hack comes out, and PM me or something if I have left out something.



In the beginning, Ignored created the instant harvest hack, which made the crops be ready for harvest instantly. On the 6th page, he revealed his methods of finding it (which also contributed a lot to bytecode hacking in general) and then took a rest. I looked at his method, took over, and continually updated the codes. Eventually, I got tired of it, and a bunch of other people started updating the timer codes. However, it eventually stopped working after a new patch, which probably added a couple more timers to make it more server-sided. In summary, the instant harvest hack no longer works, probably because somebody from this forum posted it on the Cheat Engine forums, and obviously causing a programmer for Zynga to take notice. Anyways, unless some genius comes up with another vulnerability, this will no longer work.



This hack, AKA the "vehicle fuel hack," is still working. Credits to xtremegamer

This is of course really fun to use with the vehicle area hack. Keep in mind, you have to do these BEFORE you touch any of the vehicles in the game. Additionally, it doesn't matter what order you do these in.

You have to change both of the following:

"This makes the game skip loading the vehicle's 2x2 area defined in the gameSettings.xml file."
12 0d 00 00 5e d6 ?? 60 ?? ??
11 0d 00 00 5e d6 ?? 60 ?? ??

This is what actually changes the size.
d6 ?? ?? ?? ?? 24 02 24 01
d6 ?? ?? ?? ?? 24 xx 24 xx

Just for clarification, the numbers are in hex (base 16, for you math majors), so it's currently set to 2x1.

DECIMAL:_0-1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20
HEX:_____0-1-2-3-4-5-6-7-8-9-0A-0B-0C-0D-0E-0F-10-11-12-13-14

The "plot stacking hack" is working(?). Note: You may need to refresh once or twice to get it working.

Here is an updated one.
d0 30 60 ?? 5d ?? ?? d1 d2 46 ?? ?? ?? d3 46 ?? ?? ??
02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 27

Okay, here's how I got it working:

• Open up Cheat Engine 5.5
• Open up FarmVille in your browser window.
• Attach the FarmVille window to Cheat Engine as usual.
• Enable Speedhack and type '0' but DON'T press "Apply".
  Now this part requires some timing:
• Refresh the page and watch FarmVille load - have your Cheat Engine window next to it.
• Now just when you notice the FarmVille loading bar jumps from what looks like 45-50%, on the loading bar, to around 70%, you hit "Apply" on cheat engine ASAP. (also it loaded some of the farm even though I stopped it doing loading - but it didn't fully load - it worked for me when this happened so it's not wrong if it happens to you)
• Now, scan for Array of Bytes: d0 30 60 ?? 5d ?? ?? d1 d2 46 ?? ?? ?? d3 46 ?? ?? ??
• Change the Array of Bytes you added to: 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 27 (it will ask you to confirm to change it because the value is different - press 'Continue')
• Disable Speed Hack (now it should load FarmVille completely)

I don't know if you have to scan and change the value fast - but I did at least. It worked for me in second try.

People have also been warning not to use the stack hack in the same spot of land, or overuse this hack, or else your farm will no longer load properly.



The bug exploiting storage to get infinite exp and money has been patched and is no longer working.
Also, there were also some bugs that Milamber came up with, including the giftbox hack and the hack involving the dairy farm. These have already been patched and no longer work.


Please, if you have any concerns, either post on the older thread (Farmville), or PM me.

Note: Sorry guys, I haven't gotten around to updating/verifying all these hacks lately, I'm mainly just updating as people make suggestions in the thread, so if something does not work, then be sure to tell me!
