WTF. Fine, let's have separate, micro-optimized ASM implementations for
decoding and encoding inr MAIN.EXE, but still, all those minute
difference between OP.EXE and MAINE.EXE…
This is as far as anyone should reasonably go before decompilation;
things will get really ugly with the loading functions once the file
name is involved as well…

Funny how the actual scores are stored as little-endian gaiji strings
in the bold font, yet never actually used as such.

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.

Waiting with the `fx` parameter in TH01's calls for the decompilation
of this game's version of this function…

Since a few annoying alignment bytes suggested more translation units
than previously expected, using many small headers has proved to be
better than one big shared TH04/TH05 header file. Or should we *really*
pepper the code with lots of `#pragma codestring`? 😛
And in case we have multiple translation units which all #include the
same set of headers, we'll just go with situational shared headers,
using a common prefix.

Should have remembered this from all the times I've looked at the list
of #pragma directives supported by Turbo C++… Still, I would have at
least expected a warning, but not even the `ill` warning covers this.

As used for the title screen fade-in effect. Another function that
apparently was deliberately written to run not that fast, by blitting
each row individually to the 400th VRAM row just so that it can then
turn on the EGC, perform the *actual* masked blit to the VRAM
destination, and then turn the EGC off before moving to the next now.
The same effect could have entirely been accomplished by copying
graph_pack_put_8() and applying the mask there; it's not like ZUN
didn't know how to modify master.lib…
(See also 44ad3eb4) --Nmlgc
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?
*Finally*. We already used `(unsigned) int` in quite a few places where
we actually want a 16-bit value, which was bound to annoy future port
developers.
