PS1 (single motor) rumble not working, at least on PS2 console via backward compatibility
I use a PSUnoRetro device (from willsconsolemodifications.co.uk) running BlueRetro, with a PlayStation 2 console and a DualShock 4 controller. I have enabled BlueRetro rumble via the web config, and it works for PS2 games.
I have noticed that there's no rumble at all for Porsche Challenge PAL - a PS1 game working on the PS2's backwards compatibility. Using a wired DualShock 2 pad rumble does indeed work, so it might logically be expected to work with BlueRetro.
However it does feel as if only the right-hand vibration motor is used when using a real DualShock 2 pad. From memory of owning this game back in the day, and the PS1 Dual Analog controller, I believe this game was one of the first to support that type of controller.
In a somewhat strange decision by Sony, the Dual Analog controller had its rumble motor removed for the US and European markets before it launched, but it did have a single rumble motor in Japan (https://en.m.wikipedia.org/wiki/Dual_Analog_Controller). So it would make sense that this game supports only one vibration motor, even if the feature only worked with the Japanese Dual Analog pad, and later with the DualShock and DualShock 2 controllers, themselves enhancements of that original design which remain backwards compatible with it.
Supporting this theory, Porsche Challenge is described here as being a game which indeed included support for the single vibration motor of the Dual Analog controller: https://en.m.wikipedia.org/wiki/DualShock
So... is it the case that the current BlueRetro rumble implementation only activates a DualShock 4 controller's vibration motors when output for the left-hand DualShock 2 motor is requested, and perhaps ignores requests for the right-hand motor only? Or is there some other problem breaking vibration support for Porsche Challenge specifically?
I originally raised this as a query inside another issue ticket here: https://github.com/darthcloud/BlueRetro/issues/20#issuecomment-976030915
I updated that I have seen the same issue in Gran Turismo PAL so it doesn't seem to be isolated to Porsche Challenge.
@darthcloud confirmed that it should be working, a single motor request should indeed trigger BlueRetro to rumble.
My PS2 is a model SCPH-90003 super slim (with built-in PSU), and I have updated to BlueRetro 1.2.2. This version remains affected by the issue.
BlueRetro's PS2 rumble support is incomplete. This is noted in issue 20. Hopefully it'll get fixed soon.
Any update on this? For a device targeting retro systems, complete PS2 support is surely a fairly important goal?

Darthcloud hasn’t responded to any posts regarding this issue so don’t expect it to get fixed. I don’t use Blueretro for PS1 or PS2 because of it.
