Changing Select+X on Classic N64 Controller

[Lu5id]

Hi guys -

Pretty novice with all this stuff so hopefully you stick with me - I looked through the forums and while there are many similar posts I couldn't find one that quite fit my issue.

I'm using a classic N64 controller and it took me most of an afternoon and a night to figure out how to get into the opt/retropie/configs/n64/InputAutoCfg.ini file - I finally managed to map my keys correctly. My issue is that since the classic N64 controller has no 'X' key, my hotkey for Select+X to access Retroarch doesn't currently exist. Basically I'm trying to setup a hotkey that goes 'Ztrigger + Right bumper' opens the Retroarch menu.

My button layout looks like this currently:

; DragonRise Inc. Generic USB Joystick _START
[DragonRise Inc. Generic USB Joystick ]
plugged = True
plugin = 2
mouse = False
AnalogDeadzone = 4096,4096
AnalogPeak = 32768,32768
DPad R = axis(0+)
DPad L = axis(0-)
DPAD D = axis(1+)
DPAD U = axis(1-)
Start = button(9)
C Button U = button(0)
C Button R = button(1)
C Button D = button(2)
C Button L = button(3)
B Button = button(4)
A Button = button(5)
L Trig = button(6)
R Trig = button(7)
Z Trig = button(8)
X Axis = axis(0-, 0+)
Y Axis = axis(1-, 1+)
; DragonRise Inc. Generic USB Joystick _END

Thanks in advance! Let me know if you need more information from me to troubleshoot.

The mupen64plus emulator is not a RetroArch based core, so you cannot open the RGUI since there is none. If you wish to use RetroArch, you need to use lr-mupen64, but it's not recommenedd for a PI system, the standlone emulator has better performance.
