Check whether the game sees separate players
Start with a supported controller for each player connected to the console through its documented route. Sign in or join the game lobby and confirm that each controller moves a different player. When one controller needs an adapter for a specific layout, add it after both ordinary controller assignments are working.
Titan Two can accept multiple compatible inputs. The number of input ports is different from the number of independent players the game sees. Check which devices are contributing to the adapter’s selected output before treating an extra input port as a second player slot.
Use a shared-control route when one player needs help
PlayStation documents a console setting that lets two supported controllers act together for one player. If your goal is to help someone through a menu or a difficult section, test that native option on the supported hardware. It serves a different purpose from adding a second player to a game lobby.
When sharing a controller layout, agree on which person handles movement and which handles menu choices. Test both users pressing a control at the same time. Confirm that one person can still reach pause and back if the other controller is disconnected. For split-screen, repeat the separate-player test when the game starts.
Retest player assignments after reconnecting
Turn off one controller while paused, then reconnect it using the same method. Check whether the game returns it to the original player and whether the other controller can still operate pause. Some games handle controller reassignment inside the lobby, so verify the result in the game as well as the console menu.
