I know only how to load DBVM with originally CE6.3.

How to load DBVM with self compiled Cheat Engine6.3?

Do I have to compile anything and move it to bin folder?

I refered this topic
forum.cheatengine.org/viewtopic.php?t=549357
and compiled latest CE 6.3 without error.
I use lazarus version 1.0.8(40573) with fpc version 2.6.2

You need unsigned DBK driver.
Unsigned build of dbk64.sys , should work with unofficial cheatengine EXE

Side note: it is easier to just install a 32-bit windows version (e.g. dual boot) and use the kerneldebugger on there. This is why I still have WinXP. (dual boot: Win7 and WinXP)

if 32-bit is the only reason, you do know there is also a 32-bit windows 7 ?

Thank you for your fast reply.

I use
OS:windows 7 64 bit
CPU:i7-3770K

I got dbk64.sys and moved it to bin folder.but its not working.(I'm booting windows 7-64bit with unsigned drivers allowed).

self compiled CE shows this message.

I want to use the kerneldebbugmode.
Do I have to install 32bit os ? does it have another way ?

Run the kernelmodule unloader
Reboot
Copy the unsigned driver to the ce folder again
And try then.

Perhaps windows repaired the driver

32 bit makes it easier as you don't need dbvm then. Which is another hurdle (only a handful of systems have been verified to work)

You can ignore this one, it'll work (mostly)

But if you wish a 100% correct driver, then you need to download the windows driver foundation kit and compile the driver as well

Make sure you have no online games running. (first test it on a normal game like the tutorial)

Also, if you got the sourcecode from the svn, you might want to use lazarus 1.2

Hi

I also tryed to make DBVM work with self Compiled Cheat Engine 6.3+(at x64 System) but with no success.

I downloaded the unsigned Driver and tested it with the Original CE.
Result == Working!

Then i tested it with my self Compiled CE, after i tryed to attach the Kerneldebugger to a Process(DBVM loaded) but with an Error/Crash Message which i added below.

Do i have to change something at the Source of the latest Revision to make it work?

Here some Infos that can help you to help me:
- Self Compiled CE Version works well
- Self Compiled CE Version works with self Compiled vehdebugger
- x64 System Windows 7
- Self Compiled CE Version cant load DBVM from the Settings Button
- Unsigned Driver downloaded(System restarted to allow unsigned Driver)
- Kernelmoduleunloader used
- DBVM works well with the Original CE 6.3

Download Dbgview.exe from SYSINTERNALS SOFTWARE.
Launch it, then launch CE and try again.

Post DbgView log.

Test that cheat engine is capable of communicating with the driver
Open the [Physical Memory] process, and read out address 00000000

if it's unreadable, the driver isn't working. (drivername mismatch?)

If it's readable, restart cheat engine. Go to the about screen, and click on the "your system supports dbvm"

That will launch dbvm, which the debugger will require

make sure you have vmdisk.img and vmdisk.sig in the same folder as cheat engine.

(That is the main problem for the topic poster)

Anyhow, to compile the driver you must get the "windows driver foundation kit". Preferable a version that still has support for vista (good luck) else you may have to do some fixes

then open the "x64 free build environment" for vista (7 works too, just tested)
in there navigate to the folder where the driver is. Make sure that the folder notation does NOT contain spaces.
So not "c:\my files\dbkkernel" but "c:\myfile~1\dbkkernel"

in there execute ce.bat. It will build the version that is unsigned and copy the sys files where it assumes the cheat engine binary files are (just check the .bat file)
