Maldita Castilla joypad support

If loadmap works anything like the keymapping in xboxdrv, you might need to make a udev rule that will authenticate the input as coming from an actual keyboard for some of the more stubborn software that would otherwise ignore it. If you want to use the xboxdrv example for a reference, It's brought up in the third section here.

hiulit

@mediamogul Adafruit's Retrogame https://github.com/adafruit/Adafruit-Retrogame already does that, I think.

Is this what you mean? https://github.com/adafruit/Adafruit-Retrogame#retropie-20-compatibility

mediamogul

@hiulit

That's it. You say that you believe it was handled by default. If you're still having trouble, you may want to double check to be sure.

hiulit

@mediamogul Yeah, so the udev rule is there, as expected and Maldita Castilla still ignores the inputs :(

mediamogul

@hiulit

That's a disappointment. You might try using alternative mapping software.

hiulit

@mediamogul Can you suggest any? ;)

mediamogul

@hiulit

Sure. The ones I'm aware of are 'Joymap', 'Linux Joystick Mapper' and 'xboxdrv'.

I've put together a guide for 'xboxdrv' here if you choose to use it.

hiulit

@mediamogul Hey thanks! I'll take a look at xboxdrv then :)
I thought it was only for xbox controllers...

mediamogul

@hiulit

With a name like 'xboxdrv', who could blame you. At one time it probably only handled XBox 360 controllers. XBMC (XBox Media Center) was faced with the same identity crisis once it started supporting multiple systems. It only took them twelve years to re-brand as 'Kodi'.

@mediamogul Hey! So I started following your tutorial and I got stuck just at the beginning xD

I run:

cat /proc/bus/input/devices

and I got this:

I: Bus=0003 Vendor=04f3 Product=0103 Version=0111
N: Name="HID 04f3:0103"

U: Uniq=

and then:

ls /dev/input/by-id/

Shows me this:

usb-04f3_0103-event-if01  usb-04f3_0103-event-kbd

I'm using Adafruit's Retrogame right now. That's the only "joystick" I'm seeing here, right?
Is that a problem? Or should I delete it?
Btw, I'm using arcade controlls via GPIO, if that's of any help.

@hiulit said in Maldita Castilla joypad support:

It's registering as a keyboard event, but it should be capable of being mapped in the same way. While I have never personally attempted to, it should just be a matter of mapping the keyboard event codes to the virtual XBox controller rather than the ABS_ and BTN_ event codes mentioned in the guide.

hiulit

@mediamogul Ok, so when I run:

evtest /dev/input/event2

I get this:

Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x1 product 0x1 version 0x1
Input device name: "retrogame"
Supported events:
  Event type 0 (EV_SYN)
  Event type 1 (EV_KEY)
    Event code 1 (KEY_ESC)
    Event code 19 (KEY_R)
    Event code 21 (KEY_Y)
    Event code 28 (KEY_ENTER)
    Event code 30 (KEY_A)
    Event code 38 (KEY_L)
    Event code 45 (KEY_X)
    Event code 48 (KEY_B)
    Event code 103 (KEY_UP)
    Event code 105 (KEY_LEFT)
    Event code 106 (KEY_RIGHT)
    Event code 108 (KEY_DOWN)
Properties:
Testing ... (interrupt to exit)

And when I hit a button, I get this:

Event: time 1475954839.991566, type 1 (EV_KEY), code 19 (KEY_R), value 1
Event: time 1475954839.991566, -------------- EV_SYN ------------
Event: time 1475954840.139875, type 1 (EV_KEY), code 19 (KEY_R), value 0
Event: time 1475954840.139875, -------------- EV_SYN ------------

What should I do with this information? Because in your tutorial you mention ABS_ and BTN_ but I don't see any of that :P

How can I use these lines with the output I have?

 --evdev-absmap ABS_*=x1,ABS_*=y1,ABS_*=x2,ABS_*=y2,ABS_*=lt,ABS_*=rt,ABS_*=dpad_x,ABS_*=dpad_y \
    --evdev-keymap BTN_*=a,BTN_*=b,BTN_*=x,BTN_*=y,BTN_*=lb,BTN_*=rb,BTN_*=tl,BTN_*=tr,BTN_*=guide,BTN_*=back,BTN_*=start \

Thanks again! And sorry to bother you... :)

mediamogul

@hiulit

This is purely hypothetical, but you might be able to map the virtual XBox 360 event by changing all the ABS_ and BTN_ references to KEY_, such as:

 --evdev-absmap KEY_*=x1,KEY_*=y1 \
 --evdev-keymap KEY_*=a,KEY_*=b \

If that doesn't work then I believe you'll have to try and find mapping software that can specifically map keyboard keys to event types. One of the two other options I listed above may be capable of that, but I can't say for sure.

retronerd

can you use an 8bitdo snes30 controller and start it in keyboard mode?

mediamogul

@retronerd

I'm afraid not. Since then I've learned that while this feature is on the drawing board and has even been coded, it currently isn't implemented and there has been no development in over a year.

pjft

@hiulit hi. Did you end up sitting this out? I'm going through the exact same process with xboxdrv on another thread with @mediamogul but seem to have hit a similar roadblock.

Would love to hear your progress and status.

Thanks.

hiulit

@pjft Not on my part, I haven't been successful :(

ExarKunIv

so here is what i have found out. Maldita Castilla will not play unless it sees the controller input with a input0

i had to remove all my settings and IR input to even get it to work.

I dont know if @mediamogul knows how to get xboxdrv to set the keyboard map to input0

for me my IR input takes that spot. so this game will not work for me.

maybe there is a way to reserve that placement for different input. that is beyond me

as you see my HID it taking the input0 and this is what Maldita Castilla looks for its input. so we need to reserve this input from being taken and set it for a keyboard map.

I know this is not a answer but more info never hurts.

@ExarKunIv
Does your joystick/gamepad use this IR input?

If not try plugging in your joystick/gamepad into USB port 1 on your RPi

pjft

Oh, wow. This is definitely a great find.

I am unsure of how exactly we'll be able to systematically fix this, but knowing about this can already help narrowing down approaches to make it work.

If you start your OS with just a keyboard plugged in, and then plug in your controller, and then unplug the keyboard, will input0 be free? If you run xboxdrv from SSH, will it create a virtual pad on input0?
