Having issues with initial boot for Ventura. Build is a Ryzen 5 3600, asrock RX 6600 8gb, and a BCM94360NG wifi card. I was able to use this build with a rx 580x with no issues all the up to the latest version, but now since I switch gpu's i get the black screen. i read that you needed to add agdpmod=pikera which ive done and ive also seen that if you take off -v keepsyms=1 debug=0x100 it works as well. when i take those three off what happens is that im able to boot into the installation part, but my WIFI doesn't work. do i need to spoof it or is it something else that im missing at this point?

I unchecked a bunch of unnecessary kexts in your config and removed and added a boot-arg.
Before you do anything else, if you haven't already, update your kexts (I left checked) to the latest versions and update Open Core to at least 0.8.8.
Both your RX 6600 and the BCM94360NG card work natively in Ventura so you should have no issues. In regards to the latter I highly suspect it was unnecessary kexts that (according to your config.plist) are loading and would conflict. You do not need to spoof the BCM94360NG chipset nor load any special kexts.
