Maldon, you're the goat!
I have a MLSSE RX 590 GME (it is a frankenstein one, it has 16x 512mb memory chip mod, so the bios is totally patched, the famous "gambiarra"), i already tried changing the id like you did above, but it breaks the patches made by the seller. Can I just modify the card's ID in the opencore via config.plist? Is that possible?
Saudações do Brasil! ☺️
just in case, here is the vbios:
