Summary 08058: nbapbp, nbapbpa: Lack of player 3 and 4 inputs.
Description Only player 1 and 2 inputs are present. Players 3 and 4 require an additional I/O board that isn't hooked up. Submitting this because of no "IMPERFECT CONTROLS" flag present.
Steps To Reproduce Tab and input in game (see that no inputs for p3 and p4 are present).
Additional Information Known issue. Requires hookup or HLE of a JVS I/O board connected through the main cpu's serial port. It's current implementation isn't known to do much.

Also this command in the driver init "m_maincpu->ppc4xx_spu_set_tx_handler(write8smo_delegate(*this, FUNC(hornet_state::jamma_jvs_w)));" should only be for gradius4 and nbapbp because the rest of the games never came packaged with a JVS I/O board for controls. In fact, it's possible plugging in a JVS I/O board for the games not meant for JVS can cause problems ingame (even on actual hardware).
