JSONized a lot of the game state.

The core of it was in the byte array, but...

Much of it was in some global task-specific C structs.  I'll
wind up making the macro mess a bit worse, just to get everything
into the JSON fold... then I can go make a pass that makes things
C++ and reduces the complexity down.
