00:36 < bridge> [teeworlds] I see, strange that it even compiles 00:36 < bridge> [teeworlds] then i guess you need to remove the code that calls GL\_QUADS(e.g. create triangles instead of quads, in the ddnet code the code paths that use `g_Config.m_GfxQuadAsTriangle` will help you \: https://github.com/ddnet/ddnet) and replace glOrhto with glOrthofddnet also has code paths for `CONF_BACKEND_OPENGL_ES` but it only supports GLES 3 right now 00:36 < bridge> [teeworlds] (<@572881769641279488_=5bquakenet=5d=20piie>) 00:41 < bridge> [teeworlds] i guess it would also be easier to use GLES headers instead of `#include "SDL_opengl.h"` 00:41 < bridge> [teeworlds] Might find more potentially bugs
