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…

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…

"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
No need to declare most of these in C land if 1) it isn't even clear
yet whether we can even decompile these functions with their 2)
complex __usercall conventions, which 3) aren't even called from
outside this slice. --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…
