Retroflag GPI Case pcsx-rearmed controller config (SOLVED)

eskodisk

Been playing with the excellent gpi case for days now

For good speed psx emulation on the raspberry pi zero lr-pcsx-rearmed is not the best choice, I installed some games here but speed is not o.k. controller works

I now that the psx-rearmed emulator has better speed but in this version the controls of the gpi-case do nothing...

Has anyone come up yet with a configuration file that works.... ?????

eskodisk

It seems you can change the controls in pcsx-rearmed by entering the menu by pressing the escape key...
No escape key on the retroflag gpi case....

@eskodisk anyway to hook up a USB or Bluetooth keyboard?

@quicksilver I haven't tried beacause I don't own a retroflag case but it should work.

I said in Retroflag GPI Case pcsx-rearmed controller config:

@quicksilver I haven't tried because I don't own a retroflag case but it should work.

Sorry about the spelling error.

The Usb connector is constructed deeper in the case... Indeed connecting a keyboard would be a solution but it would need a special cable....
Help with the configuration file would be nice...

lolo

@eskodisk You can't use Bluetooth keyboard ?

dugo3number2

@lolo You should be able to but I don't have one to test it out.

I used a otg cable to connect a keyboard... Doing so seems to disable the buttons on the gpi case itself so.... still no good speed psx emulation here.... anyone succes with the non lr version of pcsx rearmed????

lolo

No, unfortunately the gpi case is detected like a X-Box 360 pad in the emulator.
And if you test PCSX-ReARMed just on the Pi Zero W... with a X-Box 360 pad you will have the same thing. The D Pad don't works, just the left analog stick works.
Ironically i've tested also with the "retroflag megapi pad" and it works. The pad is detected like a RetroFlag Wired Controller. I tested everything with the pcsx.cfg without success.
A pity because PCSX-ReARMed works very well on the Pi Zero.

Well, it's a driver problem, thanks to SinisterSpatula:

That's it,  Now you'll need a bluetooth keyboard to hit esc and setup the controller 
inputs, --Or try adding these to your pcsx.cfg

nano /opt/retropie/configs/psx/pcsx/pcsx.cfg

binddev = sdl:keys
bind return = player1 START
bind escape = player1 SELECT
bind escape = Enter Menu
bind a = player1 L1
bind c = player1 SQUARE
bind d = player1 R1
bind s = player1 CIRCLE
bind v = player1 CROSS
bind x = player1 TRIANGLE
bind up = player1 UP
bind down = player1 DOWN
bind right = player1 RIGHT
bind left = player1 LEFT
binddev = sdl:Microsoft X-Box 360 pad
bind escape = Enter Menu

#####################################

useful test commands (while the emulator is running, do them on ssh session):

cat /proc/bus/input/devices
ls /dev/input/by-id/
evtest /dev/input/event[1]

Yep, those instructions are a workaround to the issue. The D-pad on the GPi acts like an axis controller, and some older cores don't work with axis inputs. So the workaround is to use xboxdrv to map the axis to keyboard keys, and set keyboard key inputs in the core. This is not needed for any libretro cores, only standalone cores. It could also be solved in a future update from retroflag if they give us the ability to change from x-input to d-input. Let me know if I can be of help.

Great job SinisterSpatula, thanks! !

SinisterSpatula

@lolo Most welcome! And thank you for sharing it here, I just happened across the thread looking to see if there was other fixes for GPi on here that I haven't seen yet. :)

eskodisk

Wow... So far indeed solved...

Here is another way to solve the controller issue.
GPI by default works in D-pad mode. Retroflag provide a way to change D-pad to axis mode.
For new GPI model, use "START" instead of "SELECT". The power LED will change to purple and back to red.

"SELECT + D-PAD UP" for 5 seconds to enable D-PAD input mode
"SELECT + D-PAD LEFT" for 5 seconds to enable Joystick/Axis input mode

Run pcsx-rearmed and connect a bluetooth keyboard, use ESC to enter menu, change GPI to "Joystick/Axis input mode", config controller and save to "/opt/retropie/configs/psx/pcsx/pcsx.cfg".

Finally, you can add "bind \xA2 = Enter Menu" to pcsx.cfg. Then X key can be used as "ESC" to enter pcsx-rearmed menu. You don't need a keyboard in the future.

If your Gpi is a newer model, the select button was changed to the start button, so select+DPAD LEFT becomes start+DPAD LEFT.
