@corezon Not sure if you're still looking into this, but flycast vmus are stored under ~/RetroPie/BIOS/dc/. The documentation is a little fuzzy on this point, but it does talk about it:

@quicksilver

Thanks for this I may look into it. Thanks all for the assistance!

I’m running the Japanese version.

I'm running the JP version (http://redump.org/disc/43772/) is there an US version ?

@BJRetro I confirm you'll need a gpu which is vulkan capable (and it's drivers). Currently i don't think there are many SBCs who have vulkan support (probably jetson nano ? maybe odroid N2 ?).

Leave SHADERs and use OVERLAYs which simulates scanlines.

1 - install overlays from the retropie menu
2 - go to the folder:
/opt/retropie/emulators/retroarch/overlays/effects/scanlines/
take an overlay file and copy it to your computer, as well as your configuration file
3 - The overlay file is a png that can be cut into photoshop or other simpler programs. cut to fill exactly 640x480 in length.
4 - so remember in the configuration file and png file names etc where you have some resolution (example 1280x1024) you replace with 640x480

note that you are creating your 640x480 overlay from scratch

5 - enable overlays and select the one you created that has 640x480.

this is the method i found to make scanlines correctly match the pixels displayed on the screen

OBS: My english is bad, i am using google translator, i hope nothing written has got double meaning here too. Because in my post about EMULATIONSTATION LOCATION one person even complained.

The installation error is caused by

/usr/bin/ld: impossibile trovare -lGL

Do you have any 3rd party repositories enabled ? It looks like the OpenGL libraries are not found, which is not something that should happen on a normal installation.

DRI3 was the problem.

Isn't this a runtime settings for your X.org configuration ?

Actually I think it's part of the graphics or at least shader profile being used in mesa.
I have padoka's bleeding edge repository in use.. Otherwise known as unstable.
So things can go awry.. Like they did until I took a gander at the Makefile, saw some unused options, put 1 + 1 together and made some edits.. It worked a out beautifully.
Especially on the Flycast-Wince emu with the same Makefile edits. I'm playing Sega Rally 2 on 2x internal resolution, 2x br and a 4x pass xbr shaders without one hiccup.

Keep in mind this my first run with retropie x86. I decided to make small form factor emu box a month or so ago and gripped up a coffee lake NUC to guinea pig with. So everything is trial & error as I run with it.
