various unpopulated IC spaces (marked M66011FP, M66230FP, M66240FP, M66300FP, uPD4701A, 2 TLP521-4)
no dips
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.
