Payload: start an ELF loader on the PS5 first, such as elfldr, which listens on port 9021. Then open this address in a browser on a computer or phone on the same network, with your PS5's address in place of PS5. elfldr downloads the payload and runs it.

About PerfBar
It doesn't need any other payload. The author wrote it because etaHEN's own performance bars and kstuff can clash and crash the console, and says this one runs next to a normal setup without a System Software Error. It's forked from work by the etaHEN and OnionHEN people, erickdavestech's DualSense overlay and the Common FPS team.
