Kings field is a Fromsoft series for original Playstation. There was no way to remap the controls in game. It had those first person controls where L1 and R1 move left and right and L2 and R2 look down and up that were popular when the playstation controllers didn't have thumbsticks yet. Remapping the controller in Duckstation or PCSX you can play it with modern controls.
