Two Players, One Keyboard

[MoofViking]

Hey guys!

I'm currently trying to set up an arcade system using Retropie and a pair of Picade PCB boards.
I am having a lot of trouble getting them both to register as they come through as keyboard inputs, so every time I configure "Keyboard" to P1 or P2, it just mirrors them both.
I have even used the Arduino IDE to map the P2 buttons to the other end of the keyboard, but I still can't manage to get two players running at the same time through any of the Emulators.

I have tried all the approaches i can think of, even down to flashing them both to Gamepads and trying that way, but that opened up a whole other can of worms and I am far from experienced in these matters.
Before I carry on down that tough path, is there any way of getting two simultaneous players on a single keyboard?

@MoofViking My suggestion is to hardcode your player2 mappings in /opt/retropie/configs/all/retroarch.cfg.
Here is a template with comments:

# input_player2_a =
# input_player2_b =
# input_player2_y =
# input_player2_x =
# input_player2_start =
# input_player2_select =
# input_player2_l =
# input_player2_r =
# input_player2_left =
# input_player2_right =
# input_player2_up =
# input_player2_down =
# input_player2_l2 =
# input_player2_r2 =
# input_player2_l3 =
# input_player2_r3 =

I had a similar question. I have a USB HAPP arcade setup. It's working off 1 board and it's doing the same thing as MoofViking's keyboard. How would I hard code that?

Thanks
