You may be on to something here, So the Roms that boot Catalina work precisely because they don't communicate on a low level, so most likely driver can't control, but higher level stuff works because it uses different part of card/chip.So with low level initializing, the hardware components are unstable and doing wrong communications with high level. So that’s why hardware part of vbios is fake, but acceleration is the same as in other amd gpu. And that’s why Mac OS driver is working, because it can’t operate with hardware components but good with high level.
Interesting, so making it work would in theory be easier, since we don't need to make something work, but break something that "is working..."
