Some titles compute vibration for every pad but only send it over SIO to a DualShock (R4 with a presented NeGcon). A trusted mod can now hand the runtime DualShock motor values per seat; the host pad gets the louder of that and the guest's SIO motors. Values lapse 8 VBlanks after the last call and are cleared at every session reset, so nothing can stick on. Opt-in: no title that does not call it changes. PSX_RUMBLE_TRACE now also logs headless.
