[Picade] SCAN_CODE being ignored(Solved with nomap option)

[pilcherd]

Hi

I have the latest RetroPie, and installed McAirpos using the automatic retropie curl command. It is installed and does run an ELF MakeCode game, however I am having issues with keyboard and sound.

When my USB keyboard is plugged in to the Picade, I have two input events. /dev/input/event0 - USB /dev/input/event1 - Picade keyboard

I am trying to run McAirpos with the keyboard plugged in, and so I copied the Picade example and edited it to use event1, but the McAirpos log always shows it trying to use event0:

launCharc starting /home/pi/RetroPie/roms/makecode/arcade-SRP-Mission-Cleanup.elf with automatic gamepad mappings...

Highest found input event number: 2
Keyboard search hit:
cat /proc/bus/input/devices | grep -B 5 -A 5 Handlers=sysrq | grep -B 7 -A 3 -e EV=12001 -e EV=10001 | grep -B 2 -A 8 -E 'Phys=(usb\S+\/input1:1|usb\S+\/input0|[a-zA-Z0-9]{2}(:[a-zA-Z0-9]{2}){5}.*)' | tr ' ' '\n' | grep event | head -1 | tr -d [:cntrl:], Output:event0

Found 1 keyboard to configure on:
/dev/input/event0

Setting up keyboard in MakeCode Arcade game's /sd/arcade.cfg with:
SCAN_CODES=/dev/input/event0

PID not found for "arcade-SRP-Miss", trying again...
PID still not found for "arcade-SRP-Miss", game exited?
Terminating launCharc...

This is my ~/McAirpos/McAirpos/Makecode/sd/arcade.cfg file:

BTN_UP=103
BTN_DOWN=108
BTN_A=29
BTN_B=56

BTN_MENU=23

Is there a reason the SCAN_CODES line is being ignored?

Many thanks, Dave

I noticed that there is also /sd/arcade.cfg too. I just edited that to event1 and saved it, then run the launCharc command line to run the elf. The /sd/arcade.cfg gets set back to event0. Odd.

If I remove the keyboard and ssh in after a clean restart, the game refuses to start and says this in the log

pi@retropie:~ $ cat /tmp/McAirpos.log
launCharc starting /home/pi/RetroPie/roms/makecode/arcade-SRP-Mission-Cleanup.elf with automatic gamepad mappings...

Highest found input event number: 1

Found no gamepads or keyboards to configure...

Please try the "nomap" option and configure /sd/arcade.cfg manually. If stuck, please read or open a related issue at https://github.com/Vegz78/McAirpos.

With this situation, I run evtest and see this:

pi@retropie:~ $ evtest

So it looks like there is an input device and it is responding.

Hi @pilcherd,

Thanks for trying McAirpos and reaching out! Sorry that it is not working for you right away.

I believe you have 3 options that might solve your problem here on a default automatic curl installation, since Picade is registered as EV_KEY type keyboard controller. Either: -Unplug your regular keyboard when starting the game, and the auto search functionality will only find the Picade "keyboard" controllers, or -Set the option keybswap after launCharc in _essystems.cfg to use the last keyboard found instead of the first, or -Which is probably the preferred option, like @rdmueller did a while ago; set the option nomap after launCharc in _essystems.cfg and set everything in /sd/arcade.cfg manually, like you have attempted, and it will not be overwritten.

I hope any of these works for you!

Hi Vegard,

In my post above I had actually removed the USB keyboard and got a different error. Do you know why that might occur?

Thanks

I worked it out.

The nomap command line option is needed (per the instructions) to make the launCharc program use the file in /sd. So I edit the emulation station configuration launch command in here:

sudo vi /etc/emulationstation/es_systems.cfg

And added the nomap option to the launCharc line before the rom. And now it runs from the menu.

Thanks!

Glad to hear!

Happy retro games making and playing!
