Solved Game Reset

[lackyluuk]

@supernature2k hey mate not sure if I should open a new thread.
I am using the RESET script you posted in this thread for a long time. But since I have updated to 4.1 stable, the script is somehow messing up retroarch.

As soon as I press my Reset button on the console it works exactly 1 time. After this no retroarch special commands work anymore, not even on the controller (No Hotkey+Start to exit the game, reset, rewind, save, load etc.). I can still enter the RetroArch settings with Hotkey+A but then it freezes there and I have to turn off the Raspi by pull out the plug.

I think it's a script problem because the Hotkey commands work flawlessly on the controller. But once I used the Hardware Reset button with this script, all is bad. Any idea on that?

@Substring hey pal is @supernature2k not available these days? Maybe you have an idea on the topic above?

@lackyluuk I'd also ask @OyyoDams who's been working on a much more global python script to handle any kind of "known" event (which would fit with the volume change for alsa you wrote in your wiki for example).

Hi bro, I tested my script and it works fine, I can do several RESET, exit,re-enter the game and do it again.

could you please try this:

import RPi.GPIO as GPIO
import time
import socket
# addressing information of target
IPADDR = "127.0.0.1"
PORTNUM = 55355
 
# enter the data content of the UDP packet
COMMAND = "RESET"

def retroarch(nwcommand):
	try:
		s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
	except socket.error:
		print 'Failed to create socket'
		sys.exit()
	s.sendto(nwcommand, (IPADDR, PORTNUM))


GPIO.setmode(GPIO.BCM)
GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def netcmd(channel):
	retroarch(nwcommand)
    
GPIO.add_event_detect(3, GPIO.BOTH, callback=netcmd, bouncetime=500)

while True:
    time.sleep(0.2)

@supernature2k Thanks for your help. I tried as you proposed but it still doesn't work
I replaced

def netcmd(channel):
    retroarch(nwcommand)

with

def netcmd(channel):
      retroarch(COMMAND)

I can use this script only once. Really no idea why it stucks..
I also tried to close the socket with s.close

@supernature2k Hi,

I do have the same issue. Even with the simple echo -n "RESET" | nc -u -w1 192.168.1.172 55355 command from my computer, retroarch only responds to one kind of each event. I can't send the same command twice...

@oyyodams Hi

I really can't say where the issue is. If you say this cmd doesn't work, it looks like a RA problem.

But I tested my script on my 17.10.2 recalbox and I can send multiple RESET, exit game re-enter game and it still works O_o

What if you send the cmd to localhost (127.0.0.1) ?

@oyyodams

Ok so I did more tests and got strange behaviors. With the command you provided or via a simple script, RESET works 1 time only but... if you throw a QUIT, it works O_o

then I did the following:

~$ echo -n "LOAD_STATE" | nc -u -w1 192.168.1.30 55355
~$ echo -n "RESET" | nc -u -w1 192.168.1.30 55355
~$ echo -n "LOAD_STATE" | nc -u -w1 192.168.1.30 55355

1st command: success
2nd command: success
3rd command: fail

O_o

This is definitely a strange behavior from RA.
I tested this on my X86_64 recalbox, I'll do more test tonite on the rpi3 one.

[lackyluuk]

@supernature2k thanks for your effort.
for me it's also still the same. I use ocal host 127.0.0.1.
With the controller everything works fine.

[supernature2k]

@lackyluuk more to come tonite as I'm 100% sure it works on my 17.11.10.2 rpi3. Maybe smthg in the retroarch.cfg?

[OyyoDams]

@supernature2k same thing with localhost. Even with a simple python script. Like with your last example, I can send several commands if they are different, but I cannot send the same command more than one time. RA doesn't accept the same command more than once. We can talk on IRC if you want

My retroarchcustom.cfg is simple, I've juste added network_cmd_enable = true. Maybe there is something else to add, but I can't find what. I tried stdin_cmd_enable = true but it doesn't change anything.

@OyyoDams @supernature2k
Many thanks to the recalbox developer team. The commands are working great again with the new release

[supernature2k]

@lackyluuk thanks to RA team that accepted our merge request with the fix very quickly and included it in their last release

[OyyoDams]

@lackyluuk thanks to @supernature2k who found the bug, and to the RA team for the quick fix
