According to a report from ComputerBase, one of its community members named "_Nordlicht_" created a compatibility mod that enables LGA 1151 V2 (8th and 9th Gen) compatible CPUs to function on older LGA 1151 V1 (100 and 200-series) compatible motherboards. With this mod, the user was able to get a Core i9-9900K to run successfully on an ASRock Z170 Extreme6.
_Nordlicht_ used a combination of UEFI/BIOS modding software and tape to trick the CPU and motherboard into thinking they were compatible with each other. Despite the fact that both socket versions feature the exact same pin layout, some of the pins on the V2 variant perform different functions compared to their predecessors, requiring some of the CPU pins to be isolated from the socket.
