Cheat Engine

[lamafao]

So i've been using ce 6.3 64bit, then i found a game that would 100% crash whenever i tried to find out who writes/accesses the address and attaching a debugger.
Long story short, i used google, found an old ~2010 thread about the same problem, downloaded CE 6.0 alpha 64bit, and now my game doesn't crash anymore.

How do i fix my ce 6.3? And yes im using VEH debugger on both versions

You can try to create your own build of CE.

You need:
- Lazarus 1.0.14 FPC 2.6.2 (win32 or win64) or newer
- SVN client


Or you can download my custom build from here, :
https://drive.google.com/folderview?id=0BwMAnE6mjogMNXNjdHgxY1NqcEU

I suggest rev.2422_32&64bit_mod. It is "CE6.3+".

Steps:
1) Install Cheat Engine 6.3 - official build from CE homepage
2) overwrite files
3) test
4) do not publish CT files you created with this build (might not work with CE6.3)
5) you can always revert to previous version (install Cheat Engine 6.3 again and remove autorun folder)


If you have problems:
- look for DotNetDataCollector32.exe and DotNetDataCollector64.exe. You can disable it by renaming, e.g. DotNetDataCollector32.exe to dontwantyouDotNetDataCollector32.exe

- if you don't play with Java and Mono, go to autorun folder, there is java.lua, javaclass.lua, javaClassEditor.lua, monoscript.lua. Create new folder "disabled", move those files there.





PS: no warranty
PSS: in the future there will be CE6.4alpha and beta. We don't know when, there's no ETA.

Just tried rev.2422_32&64bit_mod but the game still crashes :S

Use "Reset settings" (in windows menu, CheatEngine entry)

Try disabling "override existing breakpoints when setting breakpoints" (uncheck it in CE Settings->Debugger Options)

What about CE6.1 and CE6.2 ?

[lamafao]

Couldnt understand how to reset settings, do you mean restore previous versions?

Also unchecked breakpoint thingie, game doesnt crash but i cant see any results when doing 'what writes/accesses this address', and im sure there should be a few.

Oh and i havent tried ce 6.1 or 6.2

Edit : Just tried 6.1 and 6.2 both crashed, also the amount of crap it installs with CE is crazy, even if i choose not to install them. After installing ce 6.2, it automatically closes all your firefox windows, and launch 8 chrome windows with smileys and crap.

When it shows nothing, don't click on stop but start another one. (rightclick the address and again find what accesses/write). You can do this up to 4 times

in memoryview you can watch the threads and see which debug registers are in use which can help.

oh yes, you must close the game between debugging with other ce versions, they do not work together

Also, what filesize did 6.2 have ? And did it install 6.2 or 6.3 ?

in the thread list open the top threads
Check the DR0 to DR3 registers. If all 4 contain a value then it just depends on luck on how fast you'll crash if you override them. It won't matter which ce version you use. Sometimes you might get one, sometimes it may run for 30 minutes before crashing, and sometimes it may crash instantaneously, depending on which DR is overridden and how often it is used internally

I'm guessing that you have to cooperate with DB on this:
- provide much more details: hardware, game name, OS
- output from DebugView

Maybe TeamViewer session and etc.
