@hex12 the problem is "which video driver can we use depending on the display backend"
We use the framebuffer backend (except on x86). There is hardly opengl on framebuffer, mostly opengles. Recent releases of amiberry added sdl2_ttf as a dependancy, which only works on opengl ...
I'll try later ... Much later, really have too much work on recalbox to fool around with recent releases of amiberry
