I'm wanting to do some memory editing on a game, but the game will crash on WriteProcessMemory, unless I load DBVM.

Is there a way I can load DBVM from my own code like CE would?
~ And maybe where in the source I could find this?

i take it you mean dbk32/64 instead of dbvm

the sourcecode for that is at https://github.com/cheat-engine/cheat-engine/tree/master/DBKKernel and you can compile it with tge windows ddk (6700. 16xxx or something)

the dbkfunctions.pas contains code to load and access the driver from usermode

now for the signed part: you MUST compile and optionally sign the driver yourself if you wish to use it.
The release build of the driver, which is signed, will only accept commands from exe's that have a valid .sig file, which is a hash of the .exe. (it's a precaution to make sure no malware uses it)

i'm getting a lot of errors simlilar to:
A2006: undefined symbol : rcx
This is building with MSVS though, should I do it within my win2k VM? Or is it possible to do it in VS

it's not possible to do it with VS (I use it for editor, but not compile)
You must use the win xp or win 7 build environment that the windows ddk installs

use DDK 7600.16385.1 if you can

after instalation you'll have a start->windows driver kits->wdk 76000.16385.1->Build environments
In there is the win 7 64-bit free build environment.
Use that, go to the folder where dbkkernel is and execute ce.bat

Alright! I have successively built both a 32 and 64 bit driver.
I'm about to (although inadvisable) turn off forced driver signing to test it.
