There is a lot retropie users that prefer snes gamepads, but since I prefer the Sega consoles I got a bootleg sega saturn gamepad called “Play Sega”.
To activate the 6 button layout it is required to edit the file “/opt/retropie/configs/all/retroarch-core-options.cfg”
and replace:
picodrive_input1 = "3 button pad"
picodrive_input2 = "3 button pad"
to:
picodrive_input1 = "6 button pad"
picodrive_input2 = "6 button pad"
My config file “/opt/retropie/emulators/retroarch/configs/playsegacontroller.cfg”
input_device = "USB,2-axis 8-button gamepad "
input_driver = "udev"
input_b_btn = "1"
input_y_btn = "3"
input_select_btn = "6"
input_start_btn = "7"
input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"
input_a_btn = "0"
input_x_btn = "2"
input_l_btn = "4"
input_r_btn = "5"
input_enable_hotkey_btn = "6"
input_exit_emulator_btn = "5"
