Since Demon's Souls on RPCS3 doesn't have official multiplayer anymore (original servers are down), the community has revived it through like The Archstones (formerly Yuvi's server).

It sounds like you're referring to running on the RPCS3 emulator, and you're highlighting a multiplayer feature nicknamed "Gnarly R..." — likely meaning "Gnarly Resurrection," "Gnarly Revival," or something similar.
