So, it seems 2 sides are missing. So clearly not a "negative coordinates" effect, because the missing sides are in front of each other. You can activate logs, sure. Activate...

Mmm, yeah, difficult to understand which side is drawn and wich isnt't. Maybe do a `glClear(GL_COLOR_BUFFER_BIT)` before the drawing of the skybox to have a more clear view of what...

Thos videos are interesting yes. Yes, of course, it's gl4es... Err, no, I don't think it's gl4es, as I see no reason why Bigendian would have an impact on quads->triangles....

Also, another simple test to do, is to simply swap `GL_QUADS` with `GL_TRIANGLE_FAN` because there is only 1 quad, both are the same, and GL_TRIANGLE_FAN is understood by gles2.

Yeah, well, the point is, simple QUADS are transformed in GL_TRIANGLE_FAN in gl4es. But if you force GL_TRIANGLE_FAN, no transform needed, and no transform done. Also, if you put LIBGL_BEGINEND=0,...

Is libGL.so built and in the same folder as the rest, and with the LD_LIBRARY_PATH referencing it? I assume it is (but it's better be checked twice), does libGL runs...

You are following this https://magazine.odroid.com/article/playing-modern-fna-games-on-the-odroid-platform/ right? What command line di you used when launching Stardew Valley?

Then I'm pretty sure SDL2 doesn't have OpenGL enabled. Can you check the logs of the cmake, or use `ccmake` to check that OpenGL is enabled? (maybe the guide is...

You can use the environnement variable `LD_DEBUG=libs` to see wich library is loaded, it can be usefull in this case.

Use `LD_DEBUG=libs` to check which SDL2 is loaded
