A couple of days ago I began putting together a UML diagram of the GameKit. http://dsowsy.nanorevolution.com/GameKit-UML.jpg The XGameKit seems to be the building block above it, and I have started a rudimentary test harness & framebuffer emulator, with the intention of a sound buffer emulator: being merged into the shown BVirtualGFXSound. BWindow and BDirectWindow will be dependent upon BWindow, so whoever is responsible for BWindow, please contact me so we can figure out a plan for creating the right method connections; at least in terms of stubbing code at first.
