@gare You can get RetroArch to run in verbose mode by choosing to launch with verbose logging. Seems like an issue with the audio - perhaps PulseAudio/Pipewire gets stuck ? Does it happen also with standalone emulators (i.e. Mupen64plus or PPSSPP) ?

@Alfa How did you solve the problem?

@mitu Heh, well. At least it works, right?

It's basically the same thing, but a different OS and some dependency installs.

@TPR Hey @TPR I am experiencing the same problem with my N64 roms. Did you end up fixing it? Thank you

Ok habe es selbst nun gelöst bekommen.

Habe wohl Cut Trace on Pin #18 nicht richtig durch geführt

Ok, I got it solved myself now.

I probably didn't carry out the cut trace on pin #18 correctly

Let me repeat my previous question - do you have a system override where the RetroArch settings are different for the gba system ? Is your gba system's configuration file custom/different from the default that RetroPie installs ?

Post the config file (/opt/retropie/configs/gba/retroarch.cfg) on pastebin.com. If you can, get a verbose log from RetroArch during this occurence and post it also on pastebin.com

@mitu Yes I did everything works Fine. I got a 1440p Monitor (as you probably alr know) and I switched to a 1080p Monitor everything works fine. I should prolly go check it on my 1440p Monitor again. I think the only thinks that won't load are the things happening on "console".

@Excalibas I fixed it commenting hdmi_safe 1 on config.txt

@mitu Thank you.
Only option 1 was possible for me.
My next step will be to buy a DualShock 4 gamepad.
Also, I will try to install OpenMediaVault to have NAS.

Can you post your config.txt boot configuration ? What version of RetroPie are you using ?

I was able to fix this issue. I tried a third television that it worked on. I guess retropie didn't like the refresh rate or resolution on my monitor originally? I was able to set the settings via the other TV and now everything works fine on the intended monitor.

@llivingst I ran into a similar issue when I updated a year old build on my pi 4. It would get to emulation station, but went to a blank screen when going into a game. It think it was crashing cause I could not exit back to emulation station or my video feed was gone. I know a lot of kernel changes were made, so maybe you have a custom configuration that interferes with the new kernel. But Step one would be to try switching hdmi ports. I remember that being in the wrong port did that before. If not, you might have to reimage a new build. I changed all my custom configs from overclocks to KMS drivers switched back to and still no go.

@RobbyThomas2525 Please don't open several topics for the same issue. I've merged your topics.
Please provide all the info asked in https://retropie.org.uk/forum/topic/3/read-this-first, this will help diagnosing the issue you're having.

@dankcushions Thanks a lot for the replies and for this last tip. I've learned a lot with this thread (core options are always saved if modified in-game, I should not mess with them xD, a way to revert them back to defaults...).
Br,
Dimas.
