I created an .uae file with the same name as my rom but I can't overwrite the configuration of my joystics (which are directly connected to the raspberry's GPIO controller) so I have to change configuration manually.

This is the .uae file content:

;
; *** Controller/Input Configuration
;
joyport0=joy2
joyport0_autofire=none
joyport0_mode=djoy
joyport0_mousemap=right
joyport0_friendlyname=GPIO Controller 2
joyport0_name=JOY2
;
joyport1=joy1
joyport1_autofire=none
joyport1_friendlyname=GPIO Controller 1
joyport1_name=JOY1
;
;
;
input.joymouse_speed_analog=2
input.joymouse_speed_digital=10
input.joymouse_deadzone=33
input.joystick_deadzone=33
input.analog_joystick_multiplier=15
input.analog_joystick_offset=-1
input.mouse_speed=100
input.autofire_speed=0
kbd_lang=us
;
; *** Common / Paths
;
show_leds=false

The only thing that works is... show_leds = false
Any suggestions?
