I'm slowly working on a tile based engine using Allegro (mainly for
640x480) and it has become prone to bugs. Anyway, what I'm doing is double
buffer with blitting (moving) the virtual screen around as I add new rows
of sprites. Is this faster or slower with the conventional way of just
rewriting every (compiled) sprite onto the screen buffer? I know my way
will get quite complex when I introduce parallex srolling. Sprite by
sprite is easier, but is it faster?
