Bug in 4 players, 4th player's joy not found

[CelsoCaldeira]

1st I get the binary v. 0.3 and set up(in RetroPie) accordingly using sdlid so I could get all the joys in the order I wanted, this setup worked only once, and I really don't know how or why.
Now the game only recognizes 3 players, even I changing the joy's position, my setup is 1 keyboard(I only play on keyboard) on p1 and 3 joys on other players, no matter what I do the emu finds only 3 players, my keyboard and p2 and 3. If I mess with sdlid i get keyboard and 1 joy controlling p1 at same time and others on p2 and 3 like it should be.
I thought is was some issue with retropie, so I tried the recalbox as it's 4-players oriented, I believe (which is great!)
to my surprise, the issue is the same.
The 4 players works on mame tested on tmnt2 and all fine, be in recalbox or retropie they both work.
I checked all the files on /recalbox/config/fba/ and they are all just like new, no config written on them.

# cat fba2x.cfg
[Graphics]
DisplaySmoothStretch=1
# Display Effect: 0 none, 1 scanlines
DisplayEffect=0
DisplayBorder=0
MaintainAspectRatio=1
RotateScreen=0

[Sound]

[Joystick]
# 

and the fba2x6btn.cfg it's the same output.

Can you try to launch a fba game on recalbox and check the fba2x.cfg again please. SDL ID and other should appear.

Now it wrote a config file, as follows:

cd /recalbox/configs/fba/

cat fba2x.cfg

[Graphics]
DisplaySmoothStretch=1

Display Effect: 0 none, 1 scanlines

DisplayEffect=0
DisplayBorder=0
MaintainAspectRatio=1
RotateScreen=0

The file fba2x6tbn has the same lines, therefore i will not post it here.

@HerbFargus I don't know yet, the binary version available in github is the same, and I am not getting to compile the commited sources, I sent a msg on irc to @digitalLumberjack, asking him to put an updated binary version, but if you have this new binary, or if you are compiling, could you put it online somewhere I can download it?
Thanks!
