Wow, this is the first time we're about to call any of these from C
land in ≥TH03? Found no built-in way to just uppercase an identifier
in TASM, so apparently we have to spell out the names in both lower-
and uppercase.
So, let's go back to regular, non-macro PUBLIC / PROC / ENDP code
wherever we can – for all functions introduced in ≥TH03, and for
everything that takes no parameters. It's simply not worth the
trouble.

About time I finally developed this piece of tech. Towards TH05, this
segment got more and more undecompilable ASM functions mixed inbetween
C ones. Which means that pretty much all of the current ASM land
`#include`s in that segment will have to become translation units. And
we *really* don't want an additional layer of numbered, per-binary
translation units that just `#include` maybe one or two functions.
Also yeah, no _TEXT suffix, to drive home the point that this is a
"library" segment, and not really "owned" by any one file.

No need to make the function names more complicated if we already
expressed the one subtle format difference between TH03 and TH04/TH05
in the plane layout enum.

ZUN might have gotten the impression that the EGC can *only* work with
multiples of 16 pixels per load or store? Which might explain why…

Also something that any future ReC project should be doing right at the
start. Finally, it made sense to do it here as well, because…

And with all possible .COM executables decompiled, this set of changes
reaches an acceptable scope, allowing us to *finally*…

The supposedly low-hanging fruit that almost every outside contributor
wanted to grab a lot earlier, but (of course) always just for a single
game… Comprehensively covering all of them has only started to make
sense recently 😛
Also, yes, the variable with the uppercase .CFG filename has itself a
lowercase name and vice versa…

Oh wow, caff4fe introduced wrong bytes into RES_KSO.COM by confusing
[cfg_bombs] with [credit_lives] -.- Which I didn't find out back then
because all the RES_*.COM binaries still had some different instruction
encodings anyway and I just didn't care enough to base my diff of those
files on the wrong encoding versions to notice the bug…
Whoops.

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.

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…

"bgimage" really was the best name I could come up with here, given
what it's used for. Everything else sounded way too ambiguous. Even
something like "mempage", in the meaning of "a third memory-backed
graphics page"… --Nmlgc
The pascal calling convention for TH03's input mode functions actually
sort of matters, since we have this nice function pointer type that
expects pascal.
Not applying this leak to TH03 since it would have more than one
`key_det` variable, resulting in names that are as much fanfiction as
the current ones…
