Ratchet & Clank multiplayer question

You can't run two processes at the same time in RPCS3. Meaning you can't run any VSH functionality at the same time as the game.
Furthermore, you shouldn't install CFW on RPCS3 at all as it only makes it run worse, nor package managers, as it will probably break your install, this is not a homebrewed console, this is an emulator.
Follow the Quickstart Guide instructions to set up the emulator and don't invent steps.

Also, missing log file for the run where you were supposed to accept said EULA and nothing showed up.
