Rumble with lr-beetle-psx/mupen64plus and DualShock 3

[paw]

Dear all,

How do I get rumble to work with lr-beetle-psx and a DualShock 3 controller. The controller is connected via bluetooth and is configured with the EmulationStation auto-config script. The controller buttons works.
According to Mednafen_PSX rumble is supported.
Config:

cat /opt/retropie/configs/psx/emulators.cfg 
lr-pcsx-rearmed = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-pcsx-rearmed/libretro.so --config /opt/retropie/configs/psx/retroarch.cfg %ROM%"
default = "lr-beetle-psx"
lr-beetle-psx = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-beetle-psx/mednafen_psx_libretro.so --config /opt/retropie/configs/psx/retroarch.cfg %ROM%"

The same goes for mupen64-plus. How do I get get rumble to work. My config:

cat / opt/retropie/configs/n64/InputAutoCfg.ini
; InputAutoCfg.ini for Mupen64Plus SDL Input plugin
; PLAYSTATION(R)3 Controller_START 
[PLAYSTATION(R)3 Controller]
plugged = True
plugin = 2
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
Mempak switch = button(1) 
Rumblepak switch = button(2) 
C Button D = button(13) axis(3+) 
C Button L = axis(2-) 
Z Trig = button(10) 
Start = button(3) 
Y Axis = axis(1-,1+)
DPad U = button(4) 
C Button U = button(12) axis(3-) 
A Button = button(14) 
DPad D = button(6) 
X Axis = axis(0-,0+)
R Trig = button(11) 
DPad R = button(5) 
B Button = button(15) 
DPad L = button(7) 
C Button R = axis(2+) 
L Trig = button(8) 
; PLAYSTATION(R)3 Controller_END 

button(2) is thumb-right push, according to `jstest /dev/input/js0, but pressing this button does not make a difference.

My system:

Best regards,

With default = "lr-pcsx-rearmed" I get a weak rumble in Tekken 3 (when enabled in in-game-options) and CTR. But it is way less prevalent than expected.

It seems that rumble was added in a git-commit, but the wiki is not completely up-to date.

I would still like to get rumble like to work with lr-beetle-psx .
