from this message i learn that i have to kick my ass and continue working on NativeBoost, including its OpenGL bindings.
Too bad, there is not much people who can do low level assembly + VM hacking + openGL hacking and interested in pushing NB forward and/or collaborating with me :( On 16 March 2011 00:17, Fernando Olivero <fernando.oliv...@usi.ch> wrote: > Hi Alex, i'm sad to hear that AlienOpenGL is not working for you, i'm > currently not mainting it.
