After a long hiatus development has begun again, and the scope of Macchiato Doppio has been expanded to include Objective C with SDL!
The current focus is in identifying design features that the framework will need to adequately deal with a variety of different 2D game types through the development of prototype games.
The first version of the Macchiato Doppio framework module are up on CVS. Feel free to browse them at your leasure.
Next to go up are the engine and basic modules, so keep an eye open.
Also, soon there should be documentation regarding the way all of this stuff is supposed to work! ;)
