Controller Mapping Issues: A becomes Y

kerflug

I'm having an issue with button mapping. I've done the process dozens of times through ES and never had an issue, but for some reason the mappings in ES aren't translating to the emulators in this image like they have in all of the others. I use Mike Tyson's Punchout on NES and Track and Field on Arcade to test my controls. The A button becomes the Y button in the Emulator but works as it should on the menus. I tried to configure through Retroarch with no luck either, same mapping issues. Again, i've does this dozens of times with other images and never had the issue. I know the A/B swap, but I've never had A turn into the Y button.

Any ideas?

@kerflug What 'image' is this that you speak of ?

Just the standard RetroPie install. I don’t know what’s going on. I’ve been trying out different controllers but after having this issue I went back to my base Logitech 710 and am having the trouble. Same problem with all controllers.

@kerflug Do you have any key/core re-mapping configured in RetroArch or enabled save_on_exit for the RetroArch configuration ?
Compare the button configuration of the gampad saved in /opt/retropie/configs/all/retroarch-joypads with the button values reported by `jstest' (https://retropie.org.uk/docs/RetroArch-Configuration/#determining-button-values) and correct them if there are discrepancies.

Thanks mitu, but yes to both of those.

Here is the relevant part of the Logitech cfg file

input_a_btn = "1"
input_b_btn = "0"
input_reset_btn = "0"
input_enable_hotkey_btn = "8"
input_l_y_plus_axis = "+1"
input_r2_btn = "7"
input_r3_btn = "12"
input_x_btn = "3"
input_menu_toggle_btn = "3"
input_l_x_minus_axis = "-0"
input_y_btn = "2"
input_r_x_plus_axis = "+2"

When I use jstest the presses correspond to what I have in this file, but when I play the NES (and Arcade, etc) the Y button press results in the B action.

I've gone into Retroarch and binded the keys with no luck and I do have Save on Exit activated.

Then this is most likely your problem. Disable save_on_exit and re-map your controller in RetroArch, then save the Core remapping and see if it's persistent.

Thank you, excuse my rookie question but why is Save on Exit bad?

@kerflug Read this topic on why this is not advisable and can cause problems.
