Change the default resolution to 1080p, 4k will be too much for the Pi. Add to your config.txt file:

hdmi_group=1 hdmi_mode=16

@cyperghost I am curious what line you read in the OP's text that leads you to believe that. He said '40GB of custom games/settings', but I think he means that he has put a lot of work into his current setup and wants to fix it without starting all over again.

OK, I hereby confirm that removing all the NULL characters from the /opt/retropie/configs/all/emulators.cfg file fixes the issue! Thanks!

@obliv Please add more info about your system, as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

How are you trying to open the launch options ?

This sounds like it could be the problem, I didn't have this issue before I tried to fix the login problem. I will reimage and update if that fixes it.

@alexgtorres91 What makes you think options 3-7 really exist ? That's not an order number there, it's a hotkey to activate the option next to it.

@albpara
You can try to add an ampersand after the launching line in runcommand
omxplayer -b "path/to/video/launching.mp4" > /dev/null &

@mitu said in Choose Emulator & Video mode screen menu now bugging?:

To quiesce those messages, either start the script independently (not part of the autostart.sh) or redirect the script's messages to /dev/null:

my_script 2>&1 1>/dev/null &

Thanks, yes i add this to hide the script messages.
And i add the line before emulationstation, like that it works.
I don't understand before that this file output are appearing on the user's terminal.

sudo bash -c 'echo 1 > /sys/module/bluetooth/parameters/disable_ertm' python /home/pi/retropie_bgm.py 2>&1 1>/dev/null & emulationstation

@meleu I've bumped the fav-launcher to v0.85 now
Maybe you can give it a chance. With the User Menu it is now possible to add more than one FAV-system

@mitu I think no. But i dont really know if something change or not... or if i did it wrong when I writed that lines (no error message, just go down to the next line) but still having the same problem with the blue menu "in game"
Just another stupid question for my part, .how I can restart the rasp, or the system in the command menu (this one we are working) because I don't know if need to restart or save the changes.

@columboscoat said in Any way to disable or hide the yellow controller message when launching a ROM?:

In what way is your solution better than using the RetroArch GUI?

Now I'm at my laptop and I'm able (have patience) to type better than on my Android phone...

My solution pleases my own taste because when using RGUI RetroArch dumps the current status of every single option of the running instance in the retroarch.cfg, overwriting the previous content. All those useful comments explaining what the options do will disappear.

We all know that RetroArch documentation is very scarce and scattered. I think that the retroarch.cfg skeleton is a good resource of information about the RetroArch options.
