After a lot of investigation, I didn´t found a working key configuration, online.
Also I could not access /dev/input/ to use jstest... Whatever, testing, testing, testing made the deal:
Working xBox360 wired USB Controller:
[Microsoft X-Box 360 pad]
plugged = True
plugin = 2
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
Mempak switch =
Rumblepak switch =
Start = button(9)
DPad U = hat(0 Up)
DPad D = hat(0 Down)
DPad L = hat(0 Left)
DPad R = hat(0 Right)
Z Trig = button(6)
C Button U = axis(3-)
C Button D = axis(3+)
C Button L = axis(2-)
C Button R = axis(2+)
R Trig = button(7)
L Trig = button(8)
A Button = button(0)
B Button = button(1)
X Axis = axis(0-,0+)
Y Axis = axis(1-,1+)
And to complete it, the iNext USB N64 Controller:
[Generic USB Joystick ]
plugged = True
plugin = 2
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
Mempak switch =
Rumblepak switch =
C Button D = button(2)
C Button L = button(3)
L Trig = button(4)
Start = button(9)
Y Axis = axis(1-,1+)
DPad U = hat(0 Up)
A Button = button(6)
DPad D = hat(0 Down)
X Axis = axis(0-,0+)
R Trig = button(5)
DPad R = hat(0 Right)
B Button = button(8)
DPad L = hat(0 Left)
Z Trig = button(7)
C Button U = button(0)
C Button R = button(1)
Seems all fine now, except connecting 2 N64, 1 xBox360 USB and 1 xBox Wireless-Adapter. ES displays, that no Controller is connected. They probably suck to much energy or it is related to the NesPi-Case I´m using :(
But that is another Topic :)
