N64 from 16:9 to 4:3 instead

function platform_sun50i-h618() {
cpu_armv8 "cortex-a53"
__platform_flags+=(x11 gles gles3 gles31)
}

The Orange Pi zero 3 has the same chipset, if I'm right, so they would carry the same name like that.

Not sure what to do with it, but...

I had a good day, thanks!

Your system should have the gles gles3 flags instead of x11 (which I assume it's now set by RetroPie-Setup), so that the GLES3 specific build options are applied to emulators/libretro cores.

Found it: Can I apply it to the system.sh script and reinstall emulators or should update Retropie script?

mitu

@Arrafart You should re-install with the new flags. Don't update, since RetroPie-Setup doesn't have your modifications and it won't work anyway.

Arrafart

@mitu I have amended /home/dietpi/RetroPie-Setup/scriptmodules/system.sh but the flags did not change.

I thought, maybe a visual things since i amended myself.
No changes after re-intallation of the 4 emulators.

Yes, because you haven't added the detection part. Here's your system.sh, but with detection: https://gist.github.com/cmitu/64d7e993609a3f28b58a0a1a0267d292. Try it and see if the correct platform is detected and the flags are applied.

You need to recompile RetroArch also:

[INFO] [Environ]: SET_HW_RENDER, context type: gl.
[ERROR] Requesting OpenGLES3 context, but RetroArch is compiled against OpenGL. Cannot use HW context.
[ERROR] [Environ]: SET_HW_RENDER - Dynamic request HW context failed.
[libretro ERROR] mupen64plus-next: libretro frontend doesn't have OpenGL support

Out of interest I think I found the "get" lines in the system.sh

sun50i-h618)
__platform="sun50i-h618"
;;

Victory! And in 4:3!

I feel like i will be getting picky now, but it runs choppy vs the mupen64plus standalone (that runs smoothly), it has a black bar on top+bottom and graphics took a hit.
Anything polish able? Or is this where we should draw the line for the Orange pi zero 2w?

You can look into the core options and make sure you disable any performance demanding options (upscaling, MSAA).

Arrafart

@mitu

I managed to puzzle a bit within the RetroArch menu (hotkey+north within the game), inside the core options, and restarting ES after each change. Might polish a bit more.

It came down to assuring the 1x resolution and some extra texture options for preference. It doesn't beat Mupen64plus graphics yet, but it is damn close right now.

I could also push the 4:3 top and bottom scaling within the glideN64 core options, no more black borders.

I am 95% satisfied! 🥂🙏🏻🎮

@mitu

Hey mitu, I had a clean install and added the two sections in the system.sh file within the Scriptmodules folder.

Now I'm trying to reinstall to show the correct flags, but whatever I reinstall it still shows the previous flags. 64bit gl vulkan x11

Note: 0 cores installed

What should I reinstall to update the flags correctly?

Edit: a restart helped me retrieve the flags into the RetroPie setup
