@Sanctus Alas, I don't know Batocera or its directory tree at all. Maybe you should ask this at the Batocera forums with reference to this thread. I guess you are the Sanctus over there, too?

Should I run the remaining "Remove the Old folder if it exists" and "Use Alternate background for main menu" items?

I don't know, you'll have to ask the theme author what those mean.

I tested the theme and it works fine at 640x480 (video & all), unfortunately I don't have a way to output 320x240 to test it at this low resolution.

@atariplayer I'm not sure you edited the right configuration file. What USB drive ?

Can you please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first ?

Thanks for the broken link notice, we'll try to fix it.

Yes :), that is the reason. I have changed video driver to gl, also under /opt/retropie/configs/arcade/all location, and that solved the issue. Thank you very much for support, BTW I learned a bit more around the configuration thanks to that .

@grant2258 Hi Grant - yes I think I've realised that this is the problem. The default RetroArch setup creates a virtual gamepad and binds both virtual gamepad and keyboard. I think the problem with Defender is that these mappings overlap - so the virtual gamepad is triggering as well as producing a keypress, and these are both bound to different things (eg thrust AND fire).

Thanks for your help!

Save states are supported by the lr-prosystem Libretro core - https://docs.libretro.com/library/prosystem/.

If you're using Raspbian Buster, then check out this issue - https://github.com/raspberrypi/linux/issues/2993 if you still want to use lircd.

@StigNasty said in Another total noob question:

Two questions: 1. What does this mean? 2. How do I do this?

It means you've been using a development branch of the RetroPie-Setup script and that branch (version) will be deleted, so you'll not be able to update in the future.

From the command line, execute the following:

cd $HOME/RetroPie-Setup git reset --hard git checkout master

OR

cd $HOME sudo rm -fr ./RetroPie-Setup git clone https://github.com/retropie/RetroPie-Setup

@Cosimo Daphne is still in the optional packages section - but depending on your system, it might not be available for install. Can you add the info detailed in https://retropie.org.uk/forum/topic/3/read-this-first to your post ?

@cowpuncher said in No video after update:

Related question: For the updates, when prompted "Updated underlying kernel, OS, etc" - Why does that update point to the kernel that kills the HDMI video out? Anybody else who updates their system and chooses to updated the underlying kernel/OS is going to run into the same problem. Just wondering why nobody's changed that to point back to the last kernel that doesn't kill the video.

The OS updates are not distributed by RetroPie, but are coming straight from upstream Raspbian distribution. If you have a video initialisation issue with a certain update, most likely is because of a firmware update.
Try telling the boot loader/firmware what resolution do you need by modifying the config.txt file and tweaking the video resolution parameters - see https://www.raspberrypi.org/documentation/configuration/hdmi-config.md.

What version of the Raspbian kernel are you using ? Can you run uname -a from a terminal and post the output ?

Ok. Thanks for your quick answer. I understand that my applications, parameters, etc. will be kept and I'll be able to use Retropie «as an application » (quotes mean I know it's slightly different from a usual application), along with other uses.

@retropieuser555 It's the Spectrum version hacked to run on Pac-Man hardware, yes. Obviously I know I could run that instead, but I wanted to run this.

Happily, I found the ROM eventually and you can indeed play it in Retropie by renaming it to pacman.zip and running it with (for example) lr-mame2003.

@technogeek69 sound like you have some sort of frame skip on where the games are running at 30fps vs 60. But we need to know your setup to help guide you to a solution.

@Phoenix_Rising66 I have the same problem. There’s no select button so i have to turn off the retro pie just to go to a different game, then after I do that I have to reconfigure the controller again

@VictimRLSH Yes. I often transfer savestates between raspberry pi, PC and my phone and they work if you're using the same core.

@Clyde I think Linus did a video about it to end the debate once and for all. In the end, it didn't matter because temps were the same.

@cedric5555 I tried the game in mame2003plus. Audio is not perfect but it's there. If you shoot while the intro music to level 1 is played, the music is cut until the main level 1 music starts, then it seems to be fine. With fb-neo, overall all the volume was a bit lower. when the intro music is played and you shoot, the music is not interrupted and you can't hear your shooting until the main level music starts.

I don't know which one's right, but fb-neo might be the better one. I'm using a pi4 so it might be too slow on a pi3.
