Emulator specific button remapping is overwritten by all/retroarch.cfg

[mike4001]

Hi,

I hope I am doing this correctly

1) First I created a controller profile with the retropie setup script
2) I edited the /opt/retropie/configs/all/retroarch.cfg and added at the buttom

input_player1_joypad_index = "0"
input_player1_b_btn = "2"
input_player1_y_btn = "3"
input_player1_select_btn = "8"
input_player1_start_btn = "9"
input_player1_up_axis = "-1"
input_player1_down_axis = "+1"
input_player1_left_axis = "-0"
input_player1_right_axis = "+0"
input_player1_a_btn = "1"
input_player1_x_btn = "0"
input_player1_l_btn = "4"
input_player1_r_btn = "6"

input_enable_hotkey_btn = "8"
input_exit_emulator_btn = "9"
input_menu_toggle_btn = "1"
input_load_state_btn = "0"
input_save_state_btn = "3"

As I want to change the button layout for the Gameboy (but it´s the same with other libretto emulators)

I go to /opt/retropie/configs/gb/retroarch.cfg and add

input_player1_b_btn = "3"
input_player1_y_btn = "1"
input_player1_a_btn = "2"
input_player1_x_btn = "0"

at the buttom.

And these changes do not apply in the gameboy emulator. I have to comment out the a, b, x, y buttons in the all/retroarch.cfg file in order that it recognizes the gameboy specific changes.

It seems that it loads gb/retroarch.cfg first but is then overwritten again by the
all/retroarch.cfg

Am I doing something wrong ?

Thats not quite right, and as punishment you should watch this:

But in summary, the setup in RetroPie3 is (in terms of retroarch)
– First reads this file
/opt/retropie/configs/{systemname}/retroarch.cfg
– Which pulls in this file at the point of the #include line
/opt/retropie/configs/all/retroarch.cfg
– That file, in turn applies the auto detected controller file from
/opt/retropie/emulators/retroarch/configs/{yourcontoller}.cfg

So in terms of controller settings, just edit what you want in the auto controller file. Then put your overrides as you have done in the system specific location.

A good rule of thumb, is to never alter the /all/retroarch.cfg unless you know you always want the rules in there to always apply, regardless of system or controller used. To be honest I hardly edit that file at all.

OK, thank you.

I think I understand now :)
