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

Controllers

Using Sega Master System controller via Bliss-Box 4-Play

The configuration at /opt/retropie/configs/mastersystem/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/mastersystem/"

input_joypad_driver = "linuxraw"
input_player1_joypad_index = 0
input_player2_joypad_index = 1

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

input_player1_b_btn = 1 # 1 = Start
input_player1_a_btn = 2 # 2
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: Master System Controller on Bliss-Box 4-Play port 2

input_player2_b_btn = 1 # 1 = Start
input_player2_a_btn = 2 # 2
input_player2_up_axis = -1 # D-Pad up
input_player2_down_axis = +1 # D-Pad down
input_player2_left_axis = -0 # D-Pad left
input_player2_right_axis = +0 # D-Pad right

#include "/opt/retropie/configs/all/retroarch.cfg"

Using Sega Mega Drive controller via Retro-Bit adapter

I previously used Sega Megadrive controllers for Master System games.

Evan-Amos via Wikipedia

Mega Drive	Master System
B	1 (START)
C	2
D-PAD	D-PAD
MODE	PAUSE

Notes:

• When game asks to push START, press button B / 1 (it’s NOT the start-button on PS3 or Megadrive controller)
• PAUSE button is actually on console part of Master System (not on a controller)

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

input_player1_joypad_index = 1 # RetroBitGenesisUSB-controller 1
input_player2_joypad_index = 1 # RetroBitGenesisUSB-controller 2

# Player 1: RetroBitGenesisUSB-controller 1

input_player1_a_btn = 2 # B --> 1 / START
input_player1_b_btn = 1 # C --> 2
input_player1_left_axis = -0
input_player1_right_axis = +0
input_player1_up_axis = -1
input_player1_down_axis = +1
input_player1_start_btn = 7 # MODE --> PAUSE

# Player 2: RetroBitGenesisUSB-controller 2

input_player2_a_btn = 10 # B --> 1 / START
input_player2_b_btn = 9 # C --> 2
input_player2_left_axis = -2
input_player2_right_axis = +2
input_player2_up_axis = -3
input_player2_down_axis = +3
