Has anyone got a keyboard working for Player 2 in PiFBA?

TheStrayMongrel

@meleu Ah fantastic. Sorry to ask when I'm sure is elementary to most but how do I "update pifba from source", run a shell command I assume? Thanks heaps for all the help.

Excellent, thanks @meleu will give that a go.

I assume this is not going to get lr-fba-next working with two players on one keyboard though @meleu ? Thats what I'm really after as SF3 and SFA wont work in piFBA.

rbaker

@TheStrayMongrel lr-fba-next already works on one keyboard because it's a "lr" core and therefore uses your universal retroarch config so there shouldn't be any issues.

@meleu I just updated from Source but no luck for me. Any chance you could post your fba2x.cfg? Here is mine:

[Keyboard]
# Get codes from /usr/include/SDL/SDL_keysym.h
A_1=306
B_1=32
X_1=308
Y_1=120
L_1=122
R_1=304
START_1=49
SELECT_1=53
LEFT_1=276
RIGHT_1=275
UP_1=273
DOWN_1=274
QUIT=27
#player 2 keyboard controls, disabled by default
A_2=97
B_2=115
X_2=113
Y_2=107
L_2=105
R_2=119
START_2=114
SELECT_2=102
LEFT_2=100
RIGHT_2=103
UP_2=114
DOWN_2=102

Player 1 works perfectly. Am I missing something when deciding on codes from SDL_keysym.h?

Hmm okay, will have to look further into it. Might have ballsed it up by using the Adafruit keyboard utility from the start.

TheStrayMongrel

Hey @rbaker, could you see any reason this wouldnt work?

rbaker

@TheStrayMongrel Pretty similar to mine, so it should work:

# Keyboard input, Joypad and Joyaxis will all obey the "nul" bind, which disables the bind completely, 
# rather than relying on a default.
input_player1_a = "alt"
input_player1_b = "ctrl"
input_player1_y = "space"
input_player1_x = "x"
input_player1_start = "num1"
input_player1_select = "num5"
input_player1_l = null
input_player1_r = null
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"

input_player2_a = "s"
input_player2_b = "a"
input_player2_y = "q"
input_player2_x = "k"
input_player2_start = "num2"
input_player2_select = "num6"
input_player2_l = null
input_player2_r = null
input_player2_left = "d"
input_player2_right = "g"
input_player2_up = "r"
input_player2_down = "f"

@rbaker
I tested with this file:
https://raw.githubusercontent.com/RetroPie/pifba/76ef8cc7c093db4c1150e4e1eeee24f860f53935/fba2x.cfg.template

Do you have 2 controllers? If so, try to start pifba with the keyboard AND two or more controllers plugged. Ignore the controllers and test two players on keyboard.

rbaker

@meleu Thanks!

ok, so I tried this:

Start PiFBA with keyboard in AND IPac connected. P1 disabled on Keyboard - only IPac works!

then

Remove IPac and use only Keyboard for everything. Only P1 works and pressing zero brings up FPS! Pressing 5 to start P2 does nothing. I configured the keyboard using Autodetect and have not configured anything else. I used the template but no player 2. I updated from Source. Next I'm going to try a fresh install.

@meleu Thanks! I got it going! At last! I updated from Source a second time and it worked great. No idea why the first time didn't work though. Thank you for your assistance, it's another problem ticked off for me. Does pressing Zero insert a coin AND display FPS for you too?

meleu

@rbaker I'm glad to know it!

rbaker

@meleu Ok, so it works with a keyboard perfectly. Sadly, it does not work with an Ipac2 with current firmware. This is the strange behaviour.......

With Ipac2 unplugged but with Keyboard plugged in, launch PiFBA. PiFBA has full 2 player functionality via the keyboard. Now I plug in the Ipac2 and have total control using both the Ipac2 and the keyboard. Now I unplug the Keyboard and Ipac2 maintains it's full 2 player functionality. All good.

Problem is, I now escape PiFBA and relaunch it. No two Player functionality, only one player. I plug the keyboard back in. Still no two player functionality. The only way to restore it is to launch it with the Ipac unplugged which is very odd and annoying. I am going to assume that this is to do with the fact that the Ipac is now presented as a joypad by default and not a keyboard in it's current firmware. I am not that desperate to use PiFBA as the libretro version works just fine but just as I've solved two player another problem appears......I think it's time to discard PiFBA!

meleu

@rbaker I know where the problem is. Feel free to change to the libretro solution, but I'll ask you to test it again after I correct it. I think it's important to the raspi 1 and zero owners. ;-)

rbaker

@meleu sounds promising again!

meleu

@rbaker can you try it again?
Reinstall from source and test it again...
The correction was made a few minutes ago.

rbaker

@meleu Good news! It works! I now have two player Ipac2 functionality with or without the keyboard plugged in. Genius @meleu . Thanks! So what was the issue?

So what was the issue?

Pretty similar to what I said here: https://retropie.org.uk/forum/post/14292

There is a variable in the code to count the number of controllers available.
Initially the problem was:
if no joysticks connected, pifba pretended to have one controller and used the keyboard for it.
First I fixed pifba to the "no joysticks connected" scenario only.

Then you reported that you had problems when connecting one, and only one, joystick. (Oh! How could I forget this scenario?! :D ). My last fix was to make pifba allways consider it has a minimum of 2 controllers. In other words, if zero or one joystick connected, consider to have 2 controllers (and get the keyboard configs at fba2x.cfg).

(Not sure if wrote it well. Sorry my poor english. :-) )
