+ TODO:
+ - everything is guesswork and should be taken with a grain of salt, especially the M66220FP hook up;
+ - are the correct sounds played at the right times?
+ - hopper / medal (main roadblock before it can be considered playable);
+ - at boot the game zero-fills the 0x020000-0x020fff range in the tc0091lvc VRAM space, which is currently unmapped in tc009xlvc.cpp.
+ Doesn't seem to use it afterwards, though.
