Does RetroArch support Force Feedback?

Sorry to resurrect an old thread - I’m trying to get my Bliss-Box working with either N64 or PS1 rumble in Retroarch. I’m a little confused by the discussion, and also wanted to see if there were any updates on proper support.

  1. I’m using the xinput driver.
  2. I’ve got DualShock controllers plugged into the Bliss-Box - SCPH-1200’s, to be clear.
  3. In Retroarch, I’m using the mednafen_psx_libretro core, and I have the controller type set to DualShock.

According to the documentation, as long as the joypad device supports rumble, I should be good - testing the PSX-DS controller’s rumble via the Bliss-Box API works fine.

Should this work, or am I chasing something that isn’t supported quite yet?
