Oh hey, guarding declarations with complicated types via #ifdef limits
the header files we additionally have to #include!

The TH04/TH05 BGM/SE mode setup is a good example for code where
different structure field offsets will vanish completely upon reverse-
engineering. If we continued to use the per-game ID string as the
variable name, we'd only have another game-specific "difference" there.

So many things named `score_*`, so many things named `hiscore_*`…
Let's go with `scoredat_*`, which clearly indicates that this stuff is
saved into a file, while still being only 8 characters.

At least wherever Turbo C++ and master.lib want us to use a
non-pointer, since both use uint16_t for segment values throughout
their APIs instead of the more sensible void __seg*. Maybe, integer
arithmetic on segment values was widely considered more important than
dereferencing?
This, hands down, has been the single worst stretch of decompilation so far.
Three extremely difficult functions that each still required inline assembly.
And no, this didn't even work out with any of the optimization features in
Borland C++ that aren't included in Turbo C++.
