Redream Crashes After Update [5/4/2024]

inolen

@mitu we don't have any URLs for that.

latest redream should work and the drivers (+ minor changes to launcher script) can be copied over from stable.

Is latest segfaulting for you as well?

Yes (on Buster). The latest version's redream script doesn't include the LD_LIBRARY_PATH/LIBGL_DRIVERS_PATH setup, but even with those set up to start redream.aarch32.elf, there an error during start-up:

@mitu hey, I still haven't gotten around to making another Buster setup yet.

I think the issue here is a recent shader change that depends on the GL_ARB_shader_bit_encoding extension. Can you run glxinfo on your machine and grep for that to see if its listed?

GL_ARB_shader_bit_encoding

On Bookworm it is supported in either GLES or GL mode, with Mesa 23.1. On Buster is not supported though, either by the default Mesa (19) or the 21.0.1 version (which it was shipped with redream).

inolen

@mitu gotcha, I'll submit a fallback path for without that soon.

I think I see what broke - on newer versions of Mesa, I had to explicitly enable that extension on 3.1 contexts for it to work. On older versions of Mesa, I believe it was silently working. However, when I explicitly enabled it I also added a check for its existence at startup and the older versions are failing there (as it's "unsupported").

Hi All

Just wondering if there is any update on this issue.

I updated Redream with the hope of getting Volgarr working on my arcade cabinet and all the Dreamcast stuff has stopped working.

As I don't know how long a fix would take, is there a way of downgrading back to an earlier version?

As a side note, would it be worth blocking the update on Pi 4's? If a warning had popped up I wouldn't have gone ahead with the update.

Thanks for all the time you guys put in to this, it's greatly appreciated.

@Jonnieboyrevel There's no update to fix this issue.
You can get an older version https://redream.io/download/redream.aarch32-raspberry-linux-v1.5.0.tar.gz and it should work, but if the game you tried (Volgarr) didn't work before the update with redream, then it won't work with that old version also.

Jonnieboyrevel

@mitu Thanks for coming back to me.

I've installed the older version and everything is running again.

I'll keep an eye on this topic and won't update again until there's a fix.

Thanks again

@Jonnieboyrevel How can you install it from package in the retropie system, I never had to use such method so I don't know how to do that, can you help me please?

Same question as @hunksurvivorx
Which are the steps to install redream previous working version from package manager or command line? Somebody can be so kind to enlight us?

Try:

sudo ~/RetroPie-Setup/retropie_packages.sh redream _autoupdate_
cd /opt/retropie/emulators/redream
wget https://redream.io/download/redream.aarch32-raspberry-linux-v1.5.0.tar.gz 
tar xzvf redream.aarch32-raspberry-linux-v1.5.0.tar.gz

Installs the current redream package. Broken, but creates the necessary shortcuts and etc. for RetroPie to be able to use them later.
Navigates to the install directory.
Downloads the older, working version binary archive.
Unpacks the archive.

@sleve_mcdichael Thanks a lot pal, it worked perfectly!

hunksurvivorx

@sleve_mcdichael It worked thank you so much, the version does not work with win CE games but at least I can play the non CE.

Unfortunately I can't get the 1st command line to take on my pi4. I'm new to Linux so it is likely I'm not inputting something correctly. I get this prompt after entering the command line 1 as you instructed above.
Sudo: ~/Retropie-Setup/retropie_packages.sh: command not found.

Please advise the best way for a complete newb to fix this issue. Thanks

@rudeboy03 It's case sensitive. RetroPie-Setup instead of Retropie-Setup.

You can enable ssh and connect from your PC to use copy and paste rather than manually typing.

Jonnieboyrevel

Still hoping for something official to fix this but started looking about...

Is it worth trying to use PiKiss https://github.com/jmcerrejon/PiKISS to install a newer version of Mesa and see if that works with the newer version of Redream? Or are newer mesa versions just incompatible?

My Pi is backed up now (losing Redream taught me that lesson...) so I can have a go, I just won't waste my time if there is a reason Retropie (Buster) can't use newer version.

Try using the weekly Bullseye image: https://files.retropie.org.uk/images/weekly/

From the readme file: These are automated development builds - they are not tested or supported nor should be
considered "Official" releases.

Jonnieboyrevel

@sugarfree Thanks for posting those. Unfortunately for me I have an entire arcade cabinet set up using the Buster version. Having got everything how I wanted it, I'm reluctant to try and start a new build...

However, on a slightly more positive note, I managed to find a fairly recent version of Redream on the Wayback machine. The link is here https://web.archive.org/web/20240306000057/https://redream.io/download

If you download version 1107 and install it manually it works fine with Retropie (Buster) and is pretty recent (Feb 2024 I think).

It runs the WinCE games and actually runs Volgarr the Viking which was my whole reason for updating in the first place.

Jonnieboyrevel

Just as an update. Inolen has released a new build, 1132. This appears to work OK on my Retropie (Buster) build.

I installed it manually but I assume it will work to update from source through the Retropie menu.

Thanks all for your help.
