You're right, it doesn't link to any of those. I did 'strings Worms | grep gl' and it came back with all kinds of gl calls though, including glViewport and glLoadIdentity. Does this mean it's GLES 2? SDL only? Or has some gl library statically linked? Also, it's built using the Airplay SDK if that means anything. Edit: also in strings: libGLES_CM.so libgles_cm.so libGLESv2.so libEGL.so -statically linked? Edit: also, SDLGL: Requested GL major version 1
