June 3 2011:Cheat Engine 6.1 Released:
It's time for a new release again. This mainly contains bugfixes that 6.0 introduced and implementing some old features that went missing from 5.6.1 to 6.0 (Trainer maker) The lua environment has been extended and some new features have been added that can make dissecting a program easier (for example the structure spider , last branch record recordign on Intel Fam6 and string map, comments in assembler, etc...)
Also, translation support has been added so you can now create translation files (.PO files) which can be used to translate Cheat Engine. There is already a russian translation file. If you do a translation please send them to dark_byte@hotmail.com or pm in the forum and I'll upload them to the site

32-bit 64-bit


January 10 2011:Cheat Engine 6.0 Released:
It has taken a while but the wait has been worth it: Cheat engine 6.0 has been released
It's not only a new version with some new features, but a complete port from Delphi to Freepascal/Lazarus with support for 64-bit
Of course, some features could not get implemented in this new version just yet, like the directx mess and trainer creator, but they are planned to come back in the next versions. If you need to use them, just use Cheat Engine 5.6.1 instead(Check the download page if you need it). And other features have just been stripped because they where useless (hyperscan)
Of course, new stuff has been added like the VEHDebugger, improved pointerscan speed, ability to compare to the values of a saved scan, advanced scripting, etc...etc...etc...

If you encounter bugs or have suggestions, please do not hesitate to report them. If you don't I can't fix/improve Cheat Engine

January 5 2011:Shortcut to launch Cheat Engine missing:
In case you're noticing that when you start Cheat Engine you get a message that the shortcut isn't valid anymore and Cheat Engine.exe has been deleted from your system then you've become the victim of a really crappy anti virus program. (Really, any anti virus that deletes files without user permission is crap)
This is probably also the cause for the "Error Code 2" message during install

The solution to this problem is uninstall your anti virus(McAfee in particular) and reboot. Then reinstall Cheat Engine and everything should work fine(perhaps installing a different anti virus as well, as long as it isn't McAfee)

And if you feel like it please contact that anti virus vendor (e-mail and/or forum) and let them know they should stop deleting Cheat Engine.exe (Even if their forum already has more than 100 topics about it)

also, Cheat engine 6.0 will be out any day now


Juli 1 2010:Before I forget:
Because I'm getting flooded with e-mails of people that don't check the forum, if you're using firefox and want to use Cheat Engine on a browser game, then open plugin-container.exe instead of the firefox process. (That process will only exist when the game has already been started)


June 30 2010:10 year anniversary and 5.6.1 release
Well, it's been a decade now that the first version of Cheat engine saw the light
To celebrate that fact I've released ce 5.6.1 , which is mainly a bugfix version but also has some small usability improvements, I also wanted to put out a beta version of CE 6 today but since it has an annoying bug that makes the foundlist hard to use I'll spend some more time on that first.

link: Cheat Engine 5.6.1

Fixes:

Fixed bug where ce would crash(close) on XP systems on certain type of games when opening a process

Fixed the error at "Same as first scan" when using the float type

Pointer rescan for value now accepts more than 8 characters

Fixed pointerscan for value not supporting more than 1 thread

Fixed showing the fpu in the kernelmode debugger

Fixed Decreased/Increased by %

Dissect Data now detects non-exact floating point values again

Disabled executing the aobscan when assigning a script to the table

Some disassembler fixes

Again some more DPI fixes

The byte-editor in the hexeditor window is now properly aligned at the proper height

The XMM registers are now shown for kernelmode debugging as well

Implemented the stop button for kernelmode "Find what addresses this code accesses"

Fixed error message when pressing enter and no address is selected in the addresslist

Fixed samememory regions so the last byte is now included as well

Fixed the simple-copy/paste option in settings (it now has effect)

Fixed bug where pressing alt made a lot of controls invisible in vista and later

Fixed the pointerscan bug that caused out of memory problems for the scan (Was already secretly fixed and released for 5.6 one week after the official release, but still mentioning it)


Changes:

Rightclicking on registers(multiple locations) saves them to the clipboard

The values of dissect data can now be saved to disk

Auto Assembler script entries have a small <script> text you can click for easier script editing

The commonmodulelist.txt has been updated with some extra dll's that have nothing to do with the game (thanks to psych)

AutoAssembler: You can't move the cursor beyond the end of a line anymore

Pointerscan: Pointerscanner now tells you that pressing stop is a stupid thing to do

Pointerscan: doubleclicking an pointer with invalid base now adds it anyhow. (In case the base becomes valid again later)

Several extra window positions are now saved when the option to save the position is enabled (included pointerscan and autoassembler)

CE now notifies you if it thinks there's not enough dispace left

Default pointer option is now set back to insert instead of append

Added a "Same as first scan" hotkey option

When opening a new process and chosing to disable everything now also disables entries in advanced options

January 31th 2010:Cheat Engine 5.6 Released
And again, I failed to update versions inbetween...(mainly having to do with dealing with a new dissaster every month). Of course, those that compiled the svn sourcecode did get to enjoy the new stuff earlier
Anyhow, version 5.6 is finally released and it has some neat features and opens several new possibilities for plugins to do some neat stuff
link: Cheat Engine 5.6


Changes:

Removed stealthmode. (Someone could make a plugin for this, one probably more advanced than the old one)

Pointerscanner speed has been increased a lot

New Icon (thanks to Phox from the forum)

The pointerscanner can now scan for values

The pointerscanner now lets you specify an offset list that it has to end with.

Removed the injected pointerscanner

The auto assembler now supports code outside of [enable] and [disable] sections so it affects both

Resultcount is now comma seperated (thanks to infinito)

New kernelmode debugger

Added the ability to offload the current OS to dbvm (if your cpu supports it)

The driver is now 64-bit compatible. (You will have to sign it yourself, or reboot with unsigned driver support)

Rewrote the disassemblerview

Deleting addresses from a scanresult is now a bit faster

Changed the hotkey handler to be more controllable

New heaplist that works based on dll injection instead of toolhelp32

Dissectcode now helps finding referenced strings

There's now a stacktrace visible during debugging (2 different types)

The registerview is gone as long as you're not debugging

CE now suppresses the "No disk" message when the systems searchpath is invalid

Added a common modulelist to the ce folder that you can edit. Include files that you do NOT want to go through when doing memory inspection

You can now open another pointerscanner window while another pointerscan is running and read the results.

The pointerscanner can now also scan for values

Added a string reference windows

Improved the plugin system:

    You can now add auto assembler commands

    You can now get a callback when the disassembler is being rendered

    You can now add a plugin item to the context of the disassemler

    etc...

Added (float)#, (double)# and (int)# support to the assembler, (double) is mainly usable in combination with the new DQ command though

Many thanks to everyone that reported bugs (e.g csimbi and Recifense) and suggestions.
Thanks to Psy for helping with the helpfile
And thanks to Oliver Sahr who has sent me a lot of suggestions, data and other information, which I will work through in the coming months. And probably make adjustments to the site accordingly

As for the future of CE, perhaps I can finally continue work on the 64-bit port of CE...

January 18th 2009: Cheat Engine 5.5 released
I guess I didn't officially update CE as often as I hoped, but anyhow, here's the new version: Cheat Engine 5.5
Changes:

added 'short' and 'far' override to the jump instructions. (Mainly usefull for auto assembler scripts that by default pick the far one)

copied the "Find out what addresses this code accesses" from advanced options to memory view

Made the above function display the current value so you don't have to add them first

And made it non-modal so you can do other stuff while it's working.

Improved custom scan so it can now also display the results

New speedhack implementation

New AutoAssembler window

Removed the question if you want a new scan. (You must now click on new scan yourself)

Added GlobalAlloc to the autoassembler

The dissect structure window can now be opened multiple times (for comparison)

Structures are now saved in the cheat table

The main ce window now has a menu (can be disabled in settings if you don't like it)

The processlist can now show process icons. (could be slow, so can be disabled in settings)

The settings window has been changed from tabs to a list

Added a tools menu so people can add quicklaunch apps. (e.g: calc)

Added the option to save and load tables as XML

Changed copy/pasting of entries to XML

Helpfile changed from .HLP to .CHM , also incorporated the plugin documentaion in the helpfile instead of a seperate .RTF

Added a few new functions to the plugin system and made the examples easier to understand (Mainly for helping with assembly scripts)

Added a packet editor example plugin

Assembler can now work with " and ' strings

Changed the reverse pointer scan to give more details about what is going on

The positions of the main window and memoryview can now be saved

The about window now tells you which version of dbvm is loaded if dbvm is running

If DBVM is running and you choose physical memory, it goes through dbvm's read physical memory instead of windows'

Added a floating point panel to several windows that use system context to display variables

Added the option to the memoryview hexview part to display 2 bytes, 4 byte, float or double instead of bytes

Improved the dissect data window to show addresses next to eachother

The bottom part of the memory view window (hexview) can now display as different types (byte, 2 byte, 4 byte, decimal 4 byte, float, double)

Changed the multi pointer tutorial step so it now represents a real game situation

Added the adminRequired anifest to the standalone trainer

Fixes:

Fixed the multicore scan crash

Fixed a DPI bug on several windows

Fixed a crash when loading of the symbols failed

I've also uploaded a new version of dbvm that should be more compatible with systems that have more than 4GB ram and fixed several bugs. Also started implementing an emulator for the 'hard to virtualize' sections. So for those that know the difference between an IDT and a SDT, go ahead and download dbvm

Enjoy this version, and if you encounter bugs, please let me know (forum pm/post, Bugreport or dark_byte@hotmail.com)

July 27th 2008: DBVM source
Still busy with other stuff(But I do manage to work on CE every now and then), but since some people are having trouble with DBVM on their system I've decided to open up it's sourcecode for the public, so other people can make improvements. It still needs a lot of cleanup work, and some parts could be used from other programs, or even from inside the compiler(I have this nagging feeling the whole common.c part could get removed if build in precompiled)
I've made this package to compile on a 64-bit fedora core linux distro (I myself use a cross-compiler on a 32-bit laptop to generate the 64-bit, but this should be easier for people to use) but other distros should work too
Packages needed: nasm and yasm and optionally mkisofs and rar to make a package release

Stuff that really needs some improvements:

Makefile, I know, it's not a 'standard' makefile. But it suits my needs. If anyone feels like it. Make a better one.

The linking and filling in sizes could probable be done better instead of parsing the .MAP file to find the location

Changing the hardcoded vmread/vmwrite values's with more meaningfull defines

Better support for multicore setup

The virtual machine's first sector loader+executioner may need some extra code to make it work on more systems

Some real-mode 'special' cases may need some extra work

Emulating paging speed improvement and making it work for PAE systems. Still can't figure out why PAE just refuses to work

AMD support

You can download it here.

May 25th 2008: Still alive
I've been busy with other stuff but just wanted to let you all know there's still some stuff being done. The last few days a few bugfixes for CE commited in the SVN, several forum fixes regarding avatar and signature size, still busy planning a migration to phpbb3 someday, and updated the table database to update the date when a table is updated.
Also letting you know there's still some more updates planned

January 10th 2008: DBVM bugfix
For those that know how to use it, I've updated DBVM to version 0.4. Check the downloads page.
It mainly fixes the bug where it doesn't initialize secondary cpu cores, sets the A20-line to enabled, and a possible fix for systems with 4GB or more ram.

January 1st 2008: New year, new site, new Cheat Engine 5.4

Happy 2008!
As you can see the new site is up, and also released version a new version of Cheat Engine(changes)
And always, please report bugs when you encounter them. I refuse to fix them if you don't tell me about them just to annoy you!

My good intention for this year is to try to update Cheat Engine a bit more often(if I get the chance). Anyhow, check out the bugtracker and the SVN for the latest news regarding the development of CE. There is also a wiki in the SVN so if you'd like to read it or contribute: Go here
Also, don't worry about the layout right now. May get some heavy changes in the future, but at least now I've got a better base to start with. (One change edits all pages as compared to the old site where each edit of the style or adition of the menu required editing each single file)

September 9th 2007: New design
Started with designing a new website. The new site should give a better idea about what Cheat Engine is and what it can do. Also adding some new stuff like a bugtracker, info about DBVM and even info about Cheat Engine
Right now this page is only visibile using the /newsite/ link, but soon (when ce5.4 is released) this will become the main page

April 24th 2007: Site back
Sorry for the downtime, but my host couldn't handle the ammount of visitors and died. So if you're reading this, that means the move was successfull Anyhow, check the forum for more info

September 9th 2006 Cheat Engine 5.3 released
I kinda forgot to update this mainpage in a long time. Don't think that CE is stopped, I just suck at updating websites. Anyhow, check the download page for the download

November 28th 2005: Cheat Engine 5.2 released
It has taken a while but I finally released CE 5.2

Added some shortcut keys to the main window. (ctrl+o opens a table, ctrl+s saves, and ctrl+alt+a opens the auto assembler)

Added reinterpretable addresses

Added auto assemble scripts to the auto assembler

Added auto assemble scripts to cheat tables

Added a pointer scanner

Added the ability to define structures

Added address recalculation by module in the standalone trainer as well (for code entries, standard addresses use interpretable addresses)

Added the db 'string' opcode to the assembler

Added the REGISTERSYMBOL and UNREGISTERSYMBOL functions to the auto assembler

Addresses now indicate of a address is in a static address or dynamicly allocated

Added a show checkbox and show hotkey property to the cheatlist in the auto assembler

Added a click handler to seperate cheats in the trainer maker. (clicking enables a cheat)

Made it possible to also use ce's kernel debugger for "change register on breakpoint"

Changed the code finder so it's not modal anymore. (You still can't use multiple at the same time but it'll fix some 'not so' user-friendly problems)

Changed the hyperscan injection method when windows 2000 is detected. should be more stable

Changed the save routines in the memory view to give more options when saving and loading

Fixed some assembler and disassembler bugs

Fixed "force memory to be writable" on PAE enabled systems

Fixed the bug where the module name was not saved in the cheat table of a code entry

Fixed the bug where the first character of the trainer maker user input field got replaced by a ?

Fixed float->unknown initial scan->first scan->exact value not showing the type selection

Fixed find out what ... when using access violations and clicking stop

Fixed invalid reordering of entries after delete of a entry in the trainer maker

Fixed the corrupted title and about text in the generated trainer when protection was enabled

Fixed resizing of the cheatlist after a delete in the trainer maker

Fixed one or two spell errors

Fixed the fullaccess function in the auto assembler

Fixed support for floating points in the trainer maker (difference between , and .)

Moved all symbolhandler code to one class instead of speading it all over the rest of the code

changed the copy/paste of entries to be more stable

Please, report bugs to me when you find them else I'll never fix them.
