Kronos core unable to start

I‘m trying to get the Kronos core to work on a Windows 10 x64 build. Unfortunately, whenever I try to load any content, it just brings up the cores quick menu with a list entry saying „no iteam“.

The same content works fine with other Sega Saturn cores like Beetle for example. I‘ve also added the required two bios files to a Kronos subfolder in the system folder.

Any idea what‘s going on here?

What’s the content of this file ? Only zip files containing bin+cue are working.

Looks like you’re using d3d11, right? I think Kronos is GL-only.

It is, that would explain why it is failing right after requesting the GL context. I think the content of the zip file might not be bin+cue though if it’s launching in beetle-saturn, because afaik beetle-saturn doesn’t support zipped bin+cue files.

So I‘ll have to change the driver over to GL? Gonna give that a try and report back.

So I‘ve changed the driver to OpenGL. Unfortunately, it now crashes RetroArch right when I try to load any content from the Kronos core.

Tried several dumps (cue+bin, ccd, m8u) but endresult is always a crash.

Sadly, we have similar reports on specific models of intel gpu, but without owning the devices it’s kinda hard to test and debug.

Do you have the technical knowledge to install a core manually ? If so i could try uploading and posting a custom kronos core with all debug information enabled, maybe it will lead us to a fix.

Could you test with the following custom build of the core and post the logs ?

Holy shit, it’s crashing before the rendering even start, so it’s not outputting anything from the renderer debug. Could you try again with a fresh install of retroarch ? I’m wondering if the issue isn’t coming from some parameter in your current setup.

I might have messed up with the first version of the custom core, try again with this one : https://github.com/FCare/Kronos/files/3000674/kronos_libretro.zip

Anyone has an older build based on 1.4.0 version?

The newer ones are, well, crap.

@TOMillr Ok, it confirms that it is exactly the same issue than https://github.com/FCare/Kronos/issues/419 : RA reports having a GL context but no instruction seems to pass between the core and the gpu. For now i’ve nothing more to test, i recommend you start following the issue on github, any breakthrough will most likely come from there and i might forgot about this post. On a sidenote, i also developped a core based on yabasanshiro, while yabasanshiro was clearly written for mobile devices (gles renderer + arm/aarch64 dynarec), it is running fair on desktop.

@TOMillr btw, did you try updating your gpu drivers ? Yours might be a bit old, the latest are available there : https://downloadcenter.intel.com/download/28662/Intel-Graphics-Driver-for-Windows-15-40-?product=81497
