Help configuring FBA buttons for Neo Geo games.

[DJC]

Hi, could someone know how can I map 2 buttons to act like one in FBA?
Based on GPIO controls I would like to config neo geo buttons to work like this:
Y=A
X=B
L=C
B=C
A=D
R=D
I don't know if it is possible to do this, I know that in mame I can do but don't know if in FBA this is possible, I like to play neo geo games with an "square" config like:
A B
C D,
But I have some friends that prefer to play in a "L shaped config like:
A B C
------D,
If I could config to
A B C
C D D
I could resolve the issue and never reconfigure the buttons everytime that someone loses and other parson with other preference of button order come to play.

@djc Unlike mame, fba rely on retroarch for mapping.
What you want to do is possible with retroarch 1.7.2 and above, however i don't know if recalbox bumped its retroarch version recently.

On a side note, your "square" config is kinda off.
On original hardware (neocd gamepad) it was :
C D
A B
On recent hardware (playstation and the such) it is :
A C
B D
Those 2 mappings are presets available through the Classic/Modern device type in "Quick Menu > Controls"

@barbudreadmon we will bump RA with FBA ;) 1.7.2 is ok, havven't tried 1.7.3 as it was out a few days before my holidays
