Yes that is all that I left in there. I removed the others. If you need the others for internet, wifi etc.. replace them as you need. I have found that sometimes doing audio for example can effect VGA. So try this alone if you can and then add until it breaks if needed.
My monitor is connected through HDMI port.
maybe that's why I'm stuck on boot?
I don't know why Hackintool detected as VGA

VGA is the standard name for the graphics card, if you can get a clean DSDT we can rename to GFX0.
Did you clean Nvram?

Yes I cleaned the NVRAM, and still would get stuck on "applekeystore..."
It only booted completely again after I remove these 2 lines:
<key>device_type</key>
<string>VGA compatible controller</string>
But still the same "7mb" graphics problem

I try to get a "clean DSDT"

Can you also get me the clover settings that make it work?
