because your macOS installation crashes but since I had to struggle a bit to understand the comments in that thread I thought it might be helpful to share the steps I took to make this work.
The default setting from this repo did not work for me but since I did not want the iGPU as output I did the following:
Change the platform id value to 0300913E (Used when the Desktop iGPU is only used for computing tasks and doesn't drive a display)
Added agpmod=pikera
Removed shikigva (not sure if this matters but I saw somewhere it should not be used).
Now I got passed the black screen after the verbose output and I saw the crash described in acidanthera/bugtracker/issues/901 i.e. the MSI problem.
To solve that you need to get some info about the graphics card. The link above shows how to get that info in Windows but also mentions getting it in mac without too many details so these are the necessary steps that worked for me:
Download gfxutils and put it on your opencore installation USB.
Boot the opencore macOS installer just like a fresh install. No need to use recovery mode.
When you get to the macOS installer (where you have the options of starting DiskUtilty etc) select Terminal from the menu at the top.
Type diskutil mountDisk /dev/diskX (where X is the number of your "Install MacOS Catalina"
cd /Volumes/Image Volume/
Run ./gfxutil
Locate the entry called GFX0, it looks something like this: PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)
Go back to your config.plist and create a new entry in DeviceProperties/Add with this value.
The AAPL,slot-name value is the decimal representation of the hex values for GFX0.
Add the ATY,Rom# parameter.
My updated settings look like this:
Feel free to close this issue, I just added the info in case it could help someone else.

Yeah, that’s a common problem. the PCI Root path.
My radeon VII had a different pci root path from this repo.
If you trawl back through the issues, u’ll find a reference to this issue.

In my case the first issue was that at some point the installation stopped and I just got a black screen. This was mentioned here:
