This looks like a bad EDID read from the Pi side, which translates to an incorrect resolution sent to the TV. Looks like a problem specific to LG TVs.

Try to lock the Pi to a certain resolution with the options in config.txt and configure it to ignore the EDID sent by the TV:

hdmi_group = 1 hdmi_mode = 16 hdmi_ignore_edid = 0xa5000080

Do you have a link to the TFT screen install instructions ? Post your config.txt to see how it's configured.

@Widge

That's ok.

We will have to wait until somebody else has figured it out.

@mitu thats sad, wish I knew how to code for it, as Elan Performer software takes midi-in. Great for triggering animations. Not to mention Octamed audio tracker for making music :(

Any idea what would it take to do, is it scripting or C+ coding. etc?

@mitu #FacePalm Yes, it is a 1708 model, but, I totally forgot about the pair button VS just holding the X-Box button to connect. Thank you for screwing my head on straight; sometimes you can see the forest full of trees, sometimes you can't...

@BuZz thanks, I see something like this in e.g. moonlight.sh.

Do you have any thoughts or comments on the method I use here in function enable_ vs the method in disable_ and install_ (or, on anything else)? I did it this way in enable_ because I also need to process the files individually, while the other two do them all as a group in the "for" loop:

Edit:

@sleve_mcdichael said in Script module Q - vars outside of functions?:

local autostart="$(_autostart_bgm123)" local bashrc="$(_bashrc_bgm123)" local onstart="$(_onstart_bgm123)" local onend="$(_onend_bgm123)"

I am seeing in the style guide that I should not do this when the variable is assigned by command substitution and that declaration and assignment should be in separate lines:

local autostart autostart="$(_autostart_bgm123)" local bashrc bashrc="$(_bashrc_bgm123)" local onstart onstart="$(_onstart_bgm123)" local onend onend="$(_onend_bgm123)" local file for file in "$autostart" "$bashrc" "$onstart" "$onend"; do

@Ashpool I just tried and I was able to create Files on ext4. But I will not use it anymore and copied the file per sftp to the Pi. I m using Bitvise SSH Client.worked great

@sleve_mcdichael
Ok, since I had only seen the directories when starting Skyscraper, I wasn't aware of the symlinks. In the end, this also means that I don't have to change anything in the configuration and I leave it as the default. I just want to have everything in the four directories so that I have everything together when I switch to a new version.

Maybe another question about the update, I can run Retropie-Setup-Script-Update and Basic Install from time to time without having to change or pay attention to anything else. So I'm not overwriting anything of my existing custom configuration, right?

I make backups of the whole sd-card as an image. But can I also mount the image without any problems in order to copy only the data from the four directories out again? Or do I save the image just to use it again as a whole and should I save only the directories again just in case?

There's no image/picture attached to your post - did you mean to add one ?

did not know that as well, thanx from me too @mitu

@mitu no dice unfortunately with that article. I am going to purchase a 2nd control board to deal with this. Looks relatively simple to install.

New torrent for Retropie 4.8 is up ! :)

@mitu
Yes I read the gpu setting on the pi4 is managed dynamically and is best left alone as it can harm performance increasing it.
I do try to keep everything default and use the advice in the documents.
I have been able to replicate the issue over and over. I decided to try turning off and on many different features under emulationstation settings and keep testing.
It's probally nothing to do with the issue but after turning OMX on and doing the test again so far ive managed to add hundreds of games without issue. I will create more collections and try again this has been the most successful for me so far. I can't really see why this would help as when adding games to the collections i don't give it time to start playing any video.

Update
Tested again with same setting OMX on with existing and new collections and worked fine.

Thanks Sim

@sleve_mcdichael
When downloading roms, on the page it will tell you the region like Japanese/ Europe and other regions.
Does that mean that the game was created in that country and anyone in the would can use it Or it would just be in their language.

@sleve_mcdichael Regarding non G-Net games, I was also trying to get Guardian Force (grdforce) and Soukyugurentai / Terra Diver (sokyugrt) to work in MAME 2010. I had poor results in 2016, and according to the following compatibility list 2010 should be able to run them at some capacity:

https://buildbot.libretro.com/compatibility_lists/cores/mame2010/mame2010.html

However when I try to load these games in 2010 the emulator freezes. These are stvbios games which seem to have mixed results in MAME. Yet some, such as Shienryu, will even run in MAME 2003-Plus. Just curious if anybody had success with those particular two.

@mitu I disabled it I think due to it being misused.

Still not sure why the things I was trying from command-line didn't work, but this seems to be getting the job done pretty reliably:

autostart.sh:

(vcgencmd force_audio hdmi 1 >/dev/null 2>&1; sleep 8; mpg123 -Z /home/pi/RetroPie/bgm/*.mp3 >/dev/null 2>&1) & #bgm emulationstation #auto

.bashrc (excerpt):

[[ $(tty) == "/dev/tty1" ]] && (vcgencmd force_audio hdmi 0 >/dev/null 2>&1; pkill mpg123) #bgm # RETROPIE PROFILE START

...this seems to work as intended, even though I couldn't get it to work on command-line for whatever reason. With this setup the audio channel opens in time for the music to begin, and closes again when I quit to console.

In autostart.sh, I put vcgencmd before the sleep command because when I did the other way, sometimes it would open up in time for the music but other times it wouldn't. This way it opens up and "hums" for a few seconds before the music starts, but it always starts from the first instant, so an acceptable compromise.

In .bashrc, the original guide said to put the command inside the RETROPIE PROFILE section but that whole section gets rewritten if you update bashwelcometweak; putting it outside the section preserves it even when the welcome tweak is updated.
