Input/Output  Current status: implemented (no sound)/stable Video Drawing the map onto the screen is being done in following steps (using Allegro v 3.9.33-1): Plot the background (conforming to the fog of war) Plot other objects (buildings, doodads, units), provided that they are on the map and not under fog of war Important: the drawing algorithm was copied from Allegro to video.c to allow the possibility of owner_color - the owner could have their colour drwn in units and buildings to indicate ownership - it's important to use Allegro v 3.9.33-1 - that's what I used. Plot user interface - panel, etc. Audio Not implemented yet, but Allegro will be very useful. Input (keyboard, mouse) Allegro can be used here also - it does everything.
