GP2X Flickering When Using Mmaped Screen


Try only updating the mmap'd screen on the vertical blanking period, that way it isn't try to update the lcd whilst you are changing it (resulting in flickering and/or tearing).

oh. uhm... I think I wait for vblank at every flipscreens. Do you mean something else?
Where should I wait for what in a DrawLine command?
Or should I use blitter for single pixels?
