Roadtrip! Auto/Car Setup (audio and controllers)

usmcgrunt

Hey Everyone!! The family is heading out on a long roadtrip soon and I've been accumulating parts for the kids to have some retropie fun on the way. My main concerns are audio and controllers for 4 kids....

What I want to do:

Allow up to 4 players (gauntlet, tmnt, etc)
Use KODI for some movies/music

What I have now:

Raspberry Pi 3 b (with case, microusb memory)
Power with switch ( i know ill have to perform a shutdown, luckily my cigarette lighter port is always powered for when i turn the car off)
Inverter with additional 2.5a usb plugs
Gaems M115 (portable, usb powered monitor)
micro bluetooth keyboard

Controllers... This is one area Im running into a snag....I have (4-5 xbox 360 controllers, 2 logitech wireless rumblepads, 2 usb snes pads, and a few other usb pads.

Audio - All the kids have 3.5mm headsets, but splitting 4 ways? Im guessing that will be troublesome. The Gaems monitor also has an audio 3.5 out jack for feeding audio over hdmi between it and the pi.

Back to my concerns:

?? Should I go wireless with the xbox360 controllers? or get 2 additional usb snes game pads?

?? Audio anyway to push audio to 4 players(actually 6 kids in the car)?

Thanks!!!

@usmcgrunt go wireless xbox 360. A microsft wireless usb adapter is your cheapest and best option since you already have the controllers. So both the joystick and d-pads work as the direction pad i add this to all my configs except ps1 and psp:

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/all/retroarch-joypads/"
#include "/opt/retropie/configs/all/retroarch.cfg"


input_player1_joypad_index = "0"
input_player2_joypad_index = "1"
input_player3_joypad_index = "2"
input_player4_joypad_index = "3"


input_player1_up_axis = "-1"
input_player1_down_axis = "+1"
input_player1_left_axis = "-0"
input_player1_right_axis = "+0"


input_player2_up_axis = "-1"
input_player2_down_axis = "+1"
input_player2_left_axis = "-0"
input_player2_right_axis = "+0"

input_player3_up_axis = "-1"
input_player3_down_axis = "+1"
input_player3_left_axis = "-0"
input_player3_right_axis = "+0"

input_player4_up_axis = "-1"
input_player4_down_axis = "+1"
input_player4_left_axis = "-0"
input_player4_right_axis = "+0"

@edmaul69 Thanks!!! Solved one issue there! and I have an extra 2.4 receiver too! thank you for sharing your config, which I always appreciate the work/time people have invested. Now onto researching audio....

@usmcgrunt you need a 2-way headphone splitter and a 6-way headphone splitter to get 6 headphones. Plug the 6 way into one of the plugs on the 2-way. Here is the 6-way splitters on amazon.
