I didn't get any answer to this question. Maybe they don't want to spread technical information like that... *** And -finally- would like to ask you the Big Videogames Question... is there a mode to use directly video/pointer/sound of the P900 without waiting for operating system times? I mean: a) writing directly to screen memory like the old DOS times: char *p=0xa0000000; p[177]=23; // write a pixel in screen memory b) reading directly pointer position like the in old DOS times: if(pressed()) { x=xpos(); y=ypos(); do_hit_here(x,y); } c) emitting a predefined Midi note like the old DOS times: midi_out(22, 11, 33); d) getting precise timing to wait for sprite movement: now=jiffies(); I don't care about compatibility issues or battery draining (due to continuous loop of checking for user input and similar things). I had a look at the "direct access to screen" sections of the Symbian/UIQ development kit documentation pages, but I can't figure out how to do what described before. Those four operations (well, at least the first two) would allow to recycle a bunch of old DOS VGA 320x200 game sources. ***
