it's a BUTTON it's not a problem. IMO the best way to play the lost worlds is with the fire button on a joystick and a normal Taito Spinner.don’t know if it is possible but you’ll have another problem as the LW spinners also have a switch to fire by pushing the rotary down

The original Capcom push spinners are actually really terrible for gameplay in my experience.
I don't see any reason why a Taito Spinner wouldn't work. any rotary encoded spinner should work. you may have more or less sensitivity depending on the pulses per rotation though.
