  This thread: https://retropie.org.uk/forum/topic/22392/lr-atari800-5200-artifacting-basic-and-other-guidance and the accompanying github repo with the script (https://github.com/raphkoster/lr-atari800-runcommand-onstart) maybe qualify?

  @pamput thank you for this, just noticed this last night and saw it was a known issue but didn't realize it was a setting that we could toggle off.

  @pamput yep! this was my guess. your display is defaulting to 4k, and 4k defaults to 30hz on pi4, so the transparency effect in these games, where they flicker on and off at 60hz, will not work. you can tell the pi to run 4k at 60hz, but running 4k at all is going to be less performant, so instead i would go into raspi-config and set your resolution to a 1080p 60hz mode.

  It's been a long time, but I finally figured what the issue was (sorry for the necro, but it may be useful to others). In my case it wasn't a problem of power to the HDD. I had video_threaded turned off. To fix this go to the the Retroarch options, go to video and turn this back ON. Solved.

  Autostarting Atari 5200 ROMs works with atari-800 only (not with lr-atari800)

  There seems to be a collateral problem. When I configure an Atari5200 cart in RetroArch Options to work with the 5200 system and I select any game from the Atari800 section always using the lr-atari800 emulator the same ROM I have played in the Atari5200 section pops up again and I have to go back in the RetroArch option to change the system to 400/800 for this new game if I want to play it correctly. After doing this the Atari5200 cart I have played before do not start and looking at the RetroArch Option system for this ROM is back to 400/800. How can avoid this and configure both systems independentely? Do I have to use the atari-800 emu for the 400/800 games? Thanks again.

  @roslof said in DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory: Safe to say that libvlc is leaking memory? Hard to say, but my guess it's not libvlc, the error you're reporting comes from the DRM layer, libvlc is used just to decode the video and not to render the video.

  @mitu I can personally confirm an rpi-update fixed the overscan settings on my Samsung. Obviously I don't recommend rpi-update as it can cause other system issues but in this case overscan was a specific issue it fixed for me.

  @pjwentink https://retropie.org.uk/forum/topic/3/read-this-first Please read it through carefully as it requests that you open your own topic, not necro one from 2 years ago. Appreciate the log, but also in your post please supply all the info requested in the above link. This isn't to be tedious, it will save us a lot of time troubleshooting if we know what we are working with. Nobody wants to spend all day guessing what the problem might be. Thanks!

  Are there any emulators that would take advantage of openGL ES 3.2?

  I have installed the latest version of retroarch, and it ignores the configuration of ../retroarch/autoconfig/*.cfg. Has something changed? My fault, I gave him update joypad and it blocked my configuration. I deleted it and everything worked perfect.

  Anicetus_Cer Anicetus_Cer 21 minutes ago I know this is an old topic, but I tested the given examples in previous posts and they did not work for me, that is not to say they did not work in older versions of retroarch, for the record I just tested on retroarch 4.5.9 on my retropie handheld system. To get the ingame hotkey volume control working add the following two lines to /opt/retropie/configs/all/retroarch.cfg; input_volume_up = "up" input_volume_down = "down" Below is an example excerpt showing that I added the new lines underneath there reference lines in the retroarch.cfg file, Lines starting with a hash symbol (#) mean that they will not be interpreted, and as a general rule of thumb in linux, often show what default values will be overriden by adding the new lines. #Line 602... #Increases audio volume. #input_volume_up = kp_plus input_volume_up = "up" #Decreases audio volume. #input_volume_down = kp_minus input_volume_down = "down" #Line 609... Note: I tend to use the volume control menu in emulation station to set the "master volume" for want of a better phrase then the in game volume for fine grained adjustment. Hope it helps someone, if so upvote.
