configure nes and mastersystem buttons

[octubrq]

sorry for my english .I have configured retropie with several emulators, but I would like to change the buttons on nes and master system and megadrive. Is it possible to do each one separately? . that the other emulators and have properly configured

Thats a good question.

I haven’t tried it, but it is possible.

NES, MasterSystem and MegaDrive are all configured with RetroArch with one configuration file, this means that the button config is the same.

The input file is here > /home/pi/RetroPie/configs/all/retroarchinput.cfg

You can then make separate changes to each individual emulator by editing the configuration files.

For NES the file is located here> /home/pi/RetroPie/configs/nes/retroarch.cfg

For MasterSystem > /home/pi/RetroPie/configs/mastersystem/retroarch.cfg

For MegaDrive > /home/pi/RetroPie/configs/megadrive/retroarch.cfg

In each file you will need to type out the buttons you want to change, and then bind this to a button on your controller.

Here are the commands just for the buttons.

So button B is mapped to button 0 on my joystick.
So I could change button b to 0,1,2,3,4,5….

input_player1_b_btn = 0
input_player1_a_btn = 1
input_player1_y_btn = 2
input_player1_x_btn = 3
input_player1_l_btn = 4
input_player1_r_btn = 5
input_player1_start_btn = 9
input_player1_select_btn = 8
input_player1_l2_btn = "6"
input_player1_r2_btn = "7"
input_player1_l3_btn = "11"
input_player1_r3_btn = "12"

Now your probably asking “WHICH BUTTON IS 0?” or “is Start button 6 or 7 on my controller”

Theres an easy way to find out.

Exit emulation station and go to the raspberry pi terminal
type this command

jstest /dev/input/js0
Now this will load a joystick test, press a button and you will find out which number it corresponds to.

To exit jstest press ctrl+c

Good luck!
