Settings Menu for MAME (Arcade Classics) and Consoles

 The MAME emulator “TAB Mmenu” can REMAP CONTROLS, enter the arcade's SERVICE MODE, enable CHEATS, activate arcade DIP SWITCHES and other settings.

Open the MAME menu by using 'Tab' on the wireless keyboard and navigate using directional arrows and 'Enter' to make selections.  

You may also use your PLAYER 1 JOYSTICK to open and navigate the MAME menu:

“TAB” = 'Player 1 Start' + 'Player 1 Right'
”ENTER” = 'Player 1 Start' + 'Player 1 Left' (or use pinball plunger button on far right side of control panel box)

Press "TAB" again to close menu.
