lr-reicast not loading AW/Naomi games

@mitu here ya go, big thanks so far for the help,

There's no error in your log, what I see is that it loads an OpenGL3 video context, does you card knows better (OpenGL4 maybe) ? What does the next command show ?

glxinfo | head -n 20

In other news, the project's Github page vanished again, to re-appear again as https://github.com/libretro/beetle-dc :).

@mitu i think it only supports GL3.0 it s an ATI 3690 GPU,

Yeah, skmp want to re-license reicast unilaterally, he has the rights since he made contributors sign a CLA, some contributors left the project as a result. He wanted to sue libretro for "illegal use of a fork with the name of his trademark" so we had to rename the core. Don't ask me for further comment please, i'm trying to stay away from dramas, even if there is a A LOT OF THINGS i want to say about this.

@barbudreadmon so do i just update RP script and Beetle DC will show up or will it show as Reicast?

Thanks

barbudreadmon

@flybot1050 RP needs to update its build script first, and that's not even a definitive name, just something we did in a rush 2 days ago to avoid this shitstorm, most likely it will change again.

BuZz

@barbudreadmon I have a PR waiting - but I won't merge it if there will be another rename. Thanks for the info.

johnodon

Waiting to see if there if a fix for this. I have the exact same issue on similar config (Ubuntu Server 18.04) but with an Intel GPU. Game begins to launch but eventually hang and the last output shown is exactly as below...

> new tactx
> new tactx
> JVS node 1: Storing 7 cmd bytes
> Creating per-triangle/strip renderer

When I have some time later I will post more info.

@johnodon The issue with intel GPUs is known, the only known fixes are to add Option "DRI" "2" to your xorg configuration, or to revert to mesa-17. The later might be impossible or very hard on ubuntu 18.04.

Thanks...i'll give the xorg config change a shot. FYI, I was able to run Naomi/AW games some months ago without issue on the same HW. I'm guessing I was using MESA v17 at that time.

Just in case anyone wants for future reference, here is the verbose logging. As you can see, I get stuck at the same exact point as @flybot1050 (who is using an AMD GPU).

Creating the xorg conf file did the trick...

pi@ubuntu:/$ cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"     "true"
   Option      "DRI"          "2"
   Option      "AccelMethod"  "uxa"
   #Option      "AccelMethod"  "sna"
EndSection

AMD GPU might be a different issue, i could only test the condition for the issue with intel gpu :

it happens since the mesa-18 update (reverting to mesa-17 solves it)
the only sure way to get it working again seems to be the dri2 thingy (there are other way to reduce the number of freezes, but only this one seems to prevent them totally)

flybot1050

Yeah I tried using DRI 2 on Ubuntu 18.04 and it causes the desktop UI to go mental, guessing AMD GPU's don't seem to like it :(

flybot1050

That said i popped in a Nvidia GT 8800 and got the same result,
