Some my emulators are slow / glitchy audio

Zering · 29 Dec 2020, 15:49

@lektroid I would recommend using WinSCP.

LektroiD · 29 Dec 2020, 15:52

@zering There does not appear to be a mac version of this for download, I tried 'other downloads' and no mac version there either. Cyberduck was recommended in the documentation, which is why I downloaded that.

Is there another easier way to get this file?

Make sure you enabled SSH on your PI before attempting to connect to it via SFTP/SSH.

Another option would be to copy the file to the roms folder, then copy it via file shares, from the Finder. After running the emulator, exit EmulationStation and run

cp /dev/shm/runcommand.log $HOME/RetroPie/roms/

You can find the file at \\retropie\roms, along with the rest of the rom/games folders.

LektroiD · 29 Dec 2020, 16:24

@mitu Yes, SSH was enabled as per instructions in the docs, which I have followed to the word...

I tried to enter the command by pressing F4 on the RP400 keyboard, then typing "cp /dev/shm/runcommand.log $HOME/RetroPie/roms/" and it says no such file or directory. So I tried "cp /dev/shm/runcommand.log", but it says missing destination file operand after 'cp /dev/shm/runcommand.log $HOME/RetroPie/roms/' Try 'cp --help' for more information

Are you running the cp command after running the game ? The log file is not persisted between reboots, so if you haven't run the game, there won't be any file.

@mitu I only get one chance to open that menu... I start a game, then press A on the controller, then 'L - Launch With Verbose Logging'.

@dankcushions Thanks for your reply, but this is not working. I have followed the instructions to the word, inserted all the information into Cyberduck exactly, there is nowhere to add an IP address in Cyberduck, so obviously I could not enter that, and it refuses connect.

there sure is - i use it myself:

Open Connection > Server prompt.

that's fine, but if you reboot AFTER launching the game but BEFORE attempting to access the file, it will go away. try launching the game again and then try and get the file immediately and paste us the output of the failed commands please.

Finally I have the file. This is outputted from the Vectrex emulator. I can not get one from the C64 emulator, as there is no way to shut the app down after using it, so the unit needs to be unplugged to come out of the app, meaning the log file will disappear...

Your resolution is 4k@30hz. It's a bit too much too handle for emulation - I suggest you lower your resolution to 1080p@60hz.

The Pi4 doesn't output 4k@60hz by default, if you want to still keep the 4k resolution, then enable 4k@60hz from raspi-config or add to /boot/config.txt:

hdmi_enable_4kp60=1

dankcushions · 29 Dec 2020, 16:44

@lektroid

please format your logs correctly - see https://retropie.org.uk/forum/topic/3/read-this-first ('code blocks' section). i have edited your post this time :)

Finally I have the file. This is outputted from the Vectrex emulator. I can not get one from the C64 emulator, as there is no way to shut the app down after using it, so the unit needs to be unplugged to come out of the app, meaning the log file will disappear...

are you using escape key to exit? see https://retropie.org.uk/docs/Commodore-64-VIC-20-PET/

as for your log, the problem is as i expected:

[INFO] [Video]: Timings deviate too much. Will not adjust. (Display = 30.00 Hz, Game = 50.00 Hz)
[INFO] [Video]: Game FPS > Monitor FPS. Cannot rely on VSync.
[INFO] [Video]: Video @ 3840x2160

you're using a 4k30 mode. select a 1080p60 resolution mode via raspi-config (available on the retropie settings section in emulationstation)

Hi, I cannot change the resolution, when I go into Raspi-Config I select "2 Display Options", then "D1 Resolution", and it just jumps back to the first Raspi-Config screen, and thus loops around those two menus. I tried entering the code you suggested, but the audio is still slow and glitchy.

dankcushions · 29 Dec 2020, 17:23

@lektroid you can manually set the mode in /boot/config.txt

for example, for 1080p on mine I use

hdmi_group=2
hdmi_mode=82

you could try that or

hdmi_group=1
hdmi_mode=16

these are the typical ones.

mitu · 29 Dec 2020, 17:23

As an alternative to raspi-config, you can add to your /boot/config.txt file:

hdmi_group=1
hdmi_mode=16

and remove the hdmi_enable_4kp60 line.

LektroiD · 29 Dec 2020, 17:29

@mitu said in Some my emulators are slow / glitchy audio:

Tried saving the file with the new settings, but it says the file is locked and won't let me save

mitu · 29 Dec 2020, 17:47

@lektroid How are you editing the file ? If you're using an editor from the PI, make sure you're using sudo when you start the editor, the file is not editable by the pi user, since it's a system file.

@mitu I'm plugging the SD into the mac, then using Textedit to edit the file (It's the only way I know), not sure how to use sudo?

mitu · 29 Dec 2020, 18:04

You don't need sudo if you're editing the file on macOS.

LektroiD · 29 Dec 2020, 19:57

@mitu said in Some my emulators are slow / glitchy audio:

You don't need sudo if you're editing the file on macOS.

So, what's the best way to edit it, since MacOS won't save the file?

mitu · 29 Dec 2020, 20:08

Just edit it from the Pi. Exit EmulationStation and then run

sudo nano /boot/config.txt

to edit the file. Reboot after saving the file, by running sudo reboot.
