Hi I have been porting xmoto[1] from OpenGL to SDL_gfx[2] in order to be able to play this game on the nokia 770. Thanks to the guys on irc(waite,pokute, tigert your code is not in SDL_gfx 2.0.15) I have made good progress. The main reasons for choosing SDL_gfx was actually that there was no other option. It looks like OpenVG really is something interesting and perhaps the same goes for cairo. Are the OpenVG features used anywhere in the device, how do I get started? would it be possible to run xmoto on the N800 with a cairo rendering engine, what kind of framerates can I expect if I perform full screen updates? greetings [1] http://xmoto.sourceforge.net/ xmoto [2] http://www.ferzkopp.net/joomla/content/view/19/14/ sdl_gfx [3] http://wiki.xmoto.free.fr/index.php?title=SDL_gfx the Port
