Here are my NES specific notes of my RetroPie system. The NES emulator runs on RetroArch, so you may want to check out common RetroArch stuff I posted separately.

Controllers

Using NES controller via Bliss-Box 4-Play

The configuration at /opt/retropie/configs/nes/retroarch.cfg:

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

input_remapping_directory = "/opt/retropie/configs/nes/"

input_joypad_driver = "linuxraw"
input_player1_joypad_index = 0
input_player2_joypad_index = 1

# Player 1: NES Controller on Bliss-Box 4-Play port 1

input_player1_b_btn = 1 # B
input_player1_a_btn = 2 # A
input_player1_select_btn = 5 # Select
input_player1_start_btn = 6 # Start
input_player1_up_axis = -1 # D-Pad up
input_player1_down_axis = +1 # D-Pad down
input_player1_left_axis = -0 # D-Pad left
input_player1_right_axis = +0 # D-Pad right

# Player 2: NES Controller on Bliss-Box 4-Play port 2

input_player2_b_btn = 1 # B
input_player2_a_btn = 2 # A
input_player2_select_btn = 5 # Select
input_player2_start_btn = 6 # Start

# Hot keys etc.

Using USB-connected PS3-controller & Sega Mega Drive controller via Retro-Bit adapter

I previously used PS3 controllers for NES games

PS3	SNES
□	B
X	A
SELECT	SELECT
START	START
D-PAD	D-PAD

For games supporting more than two simultaneous players, Sega Megadrive controllers can be used as controller 3 and 4.
