How to replicate the problem:

Hi guys, since last two days I'm going mad tring to setup my usb controllers:

the Autoconfiguration from Emulationstation works fine, and i can use controller without any problems inside the Emulationstation

Problem begins on Mame games, LEFT DPAD never works, I can move all the other directions and use buttons, but not go back (left).
Now seems I messed up something and neither the SELECT button or ENTER button on keyboard works anymore in any retroarch menù.

my file
/opt/retropie/configs/all/retroarch-joypads

looks like this, exactly like in the guide:

input_device = "USB gamepad "
input_driver = "udev"
input_r_btn = "5"
input_save_state_btn = "5"
input_start_btn = "9"
input_exit_emulator_btn = "9"
input_l_btn = "4"
input_load_state_btn = "4"
input_up_axis = "-1"
input_a_btn = "1"
input_b_btn = "2"
input_reset_btn = "2"
input_down_axis = "+1"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_x_btn = "0"
input_menu_toggle_btn = "0"
input_select_btn = "8"
input_enable_hotkey_btn = "8"
input_y_btn = "3"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

and in entering terminal using test command:

jstest /dev/input/js0

my pad works fine, so that the mapping correspond to the above config file.

Can some one please point me to the config files that I have to replace/delete/update in order to set a global config for my arcade games (mame4all) ?
Or to some step by step guide usefull to set my controller? Tried many times also from retroarch menù controller settings, but i'm missing something because still no results.

I have tried also "Core Input Remapping " from the same guide above, but I didn't found the same menù mentioned...

add: the problem is only with mame games, with n64 games everything works properly..could be a problem with my retropie nstallation?or missing bios?!

I've made the retroarch setup for input 30 times...!!!!!!!!! :-(
