You can use backport for MESA (24.2.8)/Vulkan 1.2.289

Now I did it properly and test it. I saw a massive performance increase for game loading and a better performance with Vulkan. Unfortunately , Vulkan 1.3 is not officially available yet for Pi, only 1.2.289 is available .You can get it only with MESA 24.3 but it should be soon.

Here's what I did :

1- Create an empty file /etc/apt/sources.list.d/debian-12-backports.list and write this inside with a file editor

deb http://deb.debian.org/debian bookworm-backports main

You must change the folder restriction first
2 - update MESA

sudo apt update && sudo apt upgrade sudo apt install -t bookworm-backports mesa-va-drivers

3- Double check your installed packages with:

dpkg-query -W | grep '~bpo'

4 - Update Vulkan if needed

sudo apt install mesa-vulkan-drivers/bookworm-backports

Note : - Do a backup first
- I also recommend to update cmake sudo apt install cmake/bookworm-backports.

@sith-lord-goz Rollback netplay, which is what is implemented in retroarch, relies on savestate determinism, like several other features (runahead, rewind, ...)

@dcaputi said in moving mame back to lr-mame:

So ignore all that and just tell me, should I give FBNeo a try?

Unlike MAME's OSD, RetroArch's Quick menu > Controls isn't good at remapping anything to anything. I have a feeling this might be a problem with your setup. Make sure you read this if you want to try anyway.

And yeah, a lot of games supported by MAME 0.274 aren't gonna be supported by FBNeo, especially 3D games. As for the differences between both emulators, they are explained here and there.

@steeluth said in Retropie ES config 3B+:

Following the guide I first installed the Bookworm from here > Raspberry Pi OS with desktop and recommended software and then retropie on top using image files provided and all went well.

You basically re-wrote the RetroPie image on the sdcard, over the newer RaspiOS image that you installed initially - while you may have the latest RetroPie version, you're still using an older version of RaspiOS (based on Debian buster).

The RetroPie image is using by default the pi user to operate, if you're using a different username, the installed front-end and emulators will not work. I advise you to re-flash the RetroPie image from the download page for your Pi model and boot it up, then continue from there. The system should reboot on the 1st start and then it will start automatically with EmulationStation.

If you want to use a newer RaspiOS, then you can install the Lite version and manually install RetroPie as described in the docs.

@mitu Yeah, I figured it shouldn't have any effect on audio output. The only audio settings I've changed are in /usr/share/alsa/alsa.conf, where 2 is the number of my audio device:

defaults.ctl.card = 2 defaults.pcm.card = 2

@mitu ok thanks for the info

@tribunal88 With all the counterfeits around, it's actually hard to be sure whether a sd card is good quality or not.
A standard OS is constantly reading/writing to the storage device (logs, background tasks, ...). Arguably this can be mostly disabled by editing your system files, but i don't think it's done by default on a retropie setup.

@JimmyFromTheBay said in Any progress being made with ZX81 emulation?:

@Folly

What is the "makefile"?

Here you can find what makefiles do.

The sourcecode of sz81 is here.
You will notice the Makefile.
I highlighted these lines to give you an impression on what can be added to the CFLAGS in order to compile the source code with for example zxpand.
To add zxpand it has to be added in the line 40 :
.... -D_DZ80_EXCLUDE_SCRIPT -DZXPAND

What are the "sdcard files" for ZXPAND?

I am not an expert on zxpand but it seems that program files are loaded from sdcard.
More info about zxpand can be found here.
You can also read that the SZ81 emulator can emulate the ZXpand+. To run a ZXpand-compatible program, you have to put the P file and its .wad file in the ZXpand_SD_Card folder.

"edit where the configure part so the binary is saver in a different folder than the standar sz81 emultor" - is that referring to these lines? function sources_sz80() { gitPullOrClone #patch and change the config directory for ZX80 sed -i 's/\"\.sz81\"/\"\.sz80\"/g' "sdl_resources.h"

no,
I meant :
function configure_sz80()

What you mention is sources part , look at the function name.

Because I have NO idea what that's all about, or what the different slashes mean. There basically isn't one part of that last line I understand :(

You can read more about what the program sed does over here.

So it looks like the answer to your question, sadly, is "Hell no" :D

Haha, I understand.
In the beginning it's all garbage.
Try to read the stuff I send you.
Hope you will understand it a little bit better.

@mitu

Thanks!
Unfortunately,

jstest /dev/input/js0

does not trigger the turbo button, so I think it is an internal controller button. All other buttons trigger.

@sugarfree Thank you!

@Robs said in Help setting up controls ZX Spectrum:

I want to be able to define some additional keys on the gamepad in addition to the kempston joystick function eg Atic Atac i want kempston plus a button to press "z" to pick up an object. I want this for only this ROM

I don't think that would work without involving an external utility like xboxdrv to remap a button combo to emit a key. Something like https://retropie.org.uk/docs/Universal-Controller-Calibration-%26-Mapping-Using-xboxdrv/.

Some games I want to use the keyboard. However some keys seem to fast forward the game or pause regardless of game. Where can I check those functions? Again I would like to define a normal keyboard for eg the hobbit

Just press the Scroll Lock key to toggle RetroArch into Game Focus mode where the keyboard is exclusively used by the emulated system, any RetroArch key bindings are ignored (incl. hotkey combos). Press Scroll Lock again to be able to regain control over RetroArch and exit. See here for a brief mention on Game Focus in RetroArch guides.

I went ahead and installed the development version and it seems like it's fixed the issues I've been having. Thanks for the help!

Please post the complete specs as asked in https://retropie.org.uk/forum/topic/3/read-this-first.

What the error message you're getting when the installation fails ?

I'd say that it's most likely broken and became read-only, thus the inability to erase the partition table and create a new one (re-partition).

@Lolonois Yes, I see it with "amixer". I never used this command. I will remember to check that everytime.

Now i'm working on the fully broken system :

I removed pulseaudio and pipewire. Now I can select vc4-hdmi-0 or vc4-hdmi-1 in Retropie audio menu and in raspi-config menu.

here is the amixer output :

Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 255 [100%] [0.00dB] Front Right: Playback 255 [100%] [0.00dB] Simple mixer control 'HDMI',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 255 [100%] [0.00dB] [on] Front Right: Playback 255 [100%] [0.00dB] [on]

Sound still not working, with hdmi-0 or hdmi-1 and PCM or HDMI in ES menu. sliders working but no sound. This time "MASTER" is stuck at 0%. I understand why now.

When I go in audio Retropie-setup Menu I can see an error during one second :

lvl0: Audio manager error: unable to open SDL audio : Alsa Couldn't open audio device: Device or ressource busy.

After there is the two hdmi choices and the working "Mixer - adjust output volume" Option.
I try to "Reset to default", reboot, nothing changes.

In raspi-config, 6-Advanced Options, A7-Audio Config, there is "No audio systems installed".

vc4-hdmi-0 and vc4-hdmi-1 are still availlable in 1-System Options, S2 Audio.

I updated SDL1 and SDL2 dependency packages in RetroPie Setup. Nothing changes.

@mitu I figured out why I ended up using Valerino's repository. I was trying to install gsplus to get a working emulator for the Apple IIgs. Are there any other emulators I could use (either from Retro-Pie Setup or Retro-Pie Extras) that could be installed as a replacement?

I backed up the RetroPie-Setup folder and deleted it. I tried re-installing the necessary cores packages to make it re-appear. At that point, I was able to update the RetroPie-Setup script to 4.8.9. I noticed that a few of my Spear of Destiny Files (Episodes 2 and 3) were missing, so I grabbed the GOG version of the game and compared the checksums again. After I added the appropriate files to the wolf3d folder, I tried reinstalling WolfSDL and it booted each of them up correctly.

Thanks for your suggestions and patience guys.
