Remap NES buttons

[joe-berndt]

Is it possible to remap the buttons for each game system?     The default mapping for NES is that the two buttons are next to each other horizontally so that (NES "B" button) is set to B and (NES "A" button) is set to A. I would like to set the buttons vertically so .....(NES "B" button) to Y  and (NES "A" button) to B.      Is it possible to change this globally for this system (only for NES) without messing with the other emulators? I hope i'm explaining this clearly.  Thanks in advance!

Hi, it's posible if you use a custom config file for the nes. it means too that you cannot get the auto configuration of the joysticks and other things like shaders etc anymore on this system : https://github.com/recalbox/recalbox-os/wiki/Custom-controller-mapping-for-specific-system-(EN)

I just opened that : https://github.com/recalbox/recalbox-os/issues/554

by the emulator menu I could not. so I had to edit the file

for anyone looking to remap buttons on a SNES controller:

1º create file in:
\192.168.1.xxx\share\system.config\retroarch\config\remaps\FCEUmm
name file: FCEUmm.rmp

input_player1_btn_b = "8"
input_player1_btn_y = "0"
input_player1_btn_a = "10"
input_player1_btn_x = "9"
input_player2_btn_b = "8"
input_player2_btn_y = "0"
input_player2_btn_a = "10"
input_player2_btn_x = "9"
input_libretro_device_p1 = "1"
input_player1_analog_dpad_mode = "0"
input_libretro_device_p2 = "1"
input_player2_analog_dpad_mode = "0"
input_libretro_device_p3 = "1"
input_player3_analog_dpad_mode = "0"
input_libretro_device_p4 = "1"
input_player4_analog_dpad_mode = "0"
input_libretro_device_p5 = "1"
input_player5_analog_dpad_mode = "0"

in SNES controller:

0= botton1
8= botton2
3= start
6=left
7=right
5=up
4=down
