Does anybody know how to configure The Final Burn Alpha (PiFBA) to allow 2 players? When using my keyboard I can hit TAB to add coins but hitting Enter only selects Player 1.

I have found the key binds online and nothing mentions player 2:

‘up arrow’ Up direction
‘down arrow’ Down direction
‘left arrow’ Left direction
‘right arrow’ Right direction
‘control’ Button 1 (starts a game in the frontend)
‘alt’ Button 2
‘space’ Button 3
‘shift’ Button 4
‘z’ Button 5
‘x’ Button 6
‘return’ Start button (starts a game)
‘tab’ Select button (opens config menu in the frontend)
‘escape’ Quit
‘L+R+SELECT’ Service Mode

Unfortunately, I do not get the front end option when launching out of emulation station so I have not been able to access the config menu referenced above. All tab does is adds coins.

Any help would be appreciated. My son and I have been looking forward to playing some Marvel VS Capcom against each other but have been unable to so far.
