I read that you could limit the bluescreens using the CE VM driver thing by going into MSCONFIG and limiting the CPUs that you use.

Is there anyway to just disable DBK loading on all 8 of my cores?

According to wiki I have "8 you only have a 16%" of crashing which is obviously aids. But I dont want to disable like 6 cores because then my pc would run slow wouldn't it?

I've tried turning the CPUs down to 1 but it still bluescreens like 80% of the time, am I just getting unlucky?

CE 6.8
Intel Core i7-7700HQ

I tried on 6.7 and it wouldn't even get the dkvm to start for some reason despite me getting it to work last year

With 6.8 I don't know then, it usually works 100% (on intel)
Make sure you don't run the intel performance boost tools

And at what point does it crash? When launching DBVM using the about screen, or when using a function?

Seems to be mostly when I save state on dolphin or when changing a value of an address

Why do you use DBVM for dolphin ? You can forget about debugging either way, and from what I heard memory access just works

Oh, not sure if you remember but I asked a while back on Sneaky Mofo's channel in comments how to use CE on dolphin and you linked me an guide.

The guide said to enable all the things in 'Extra', use 'Kernalmode debugger' and check all MEM boxes.

You also give me this lua to use:
dbk_useKernelmodeOpenProcess()
dbk_useKernelmodeProcessMemoryAccess()
dbk_writesIgnoreWriteProtection(true)

I'm not sure if I got the acronyms right but DBK and DBVM are the same thing right?

no, DBK and DBVM are very different things. DBVM is a virtual machine, DBK is the device driver that CE uses.
What this does is make use of the device driver to change memory (not sure why it'd bsod you though unless you combined it with [physical memory], which is a big nono)

Also, in 6.8 this guide is not necessary anymore. It 'should' be able to edit memory without crashing the target

So what do I need to do now in 6.8 in the options?

Scan Settings:
- I've checked every value type including custom (2byte endian and 4 byte endian)
- MEM_MAPPED checked

Debugger Options:
- VEH debugger

Extra:
- Everything checked


Which of these do I need to do/not do? I've been trying them off/on this morning and can't get it to find any addresses I know should be there.

Going to try different games later

EDIT:

Got it to work on different games although I can't find values I used to be able to. The X/Y/Z Coordinates for instance or actually just any float value whatsoever.

Float addresses appear when I do unknown initial value scans but never the address I'm looking for

Are integers found using big endian types? (Values bigger than 255 that is) If so, perhaps it's a big endian float?

What you find with unknown initial value for 4 bytes and then changed/unchanged (don't bother with increased/decreased on big endian, or with floats in general)

eventually you will find things related to the x,y,z coordinate. You just have to find a way to figure out the meaning of those values

I didn't even realise you could have float big endians, my cheat table from last year just uses float addresses. I'll have a further look into it.
