nmlgc 0ffa756cae [Contributing] Decide on `seg` and `off` for x86-segment-related identifiers
I could have equally argued the opposite way, and in favor of `sgm` and
`ofs`, but I've also been using `seg` and `off` more prevalently
throughout the years.

nmlgc a503ba3095 [Maintenance] [th01] Fix temporary macros
We have, in fact, already decompiled all FPU code in PC-98 Touhou.

nmlgc e1b65b6eed [Naming] [th01] MDRV2: Rename the board check function
Since it also sets an activation flag, it does much more in context
than checking for a board. This name also highlights why OP.EXE and
FUUIN.EXE ignore the BGM mode specified in the option menu.

nmlgc cf95cc8717 [Maintenance] [th01] Remove `extern "C"` from all remaining areas of code
Nothing says "we're getting things done" quite as much as this.

nmlgc 6058395372 [Maintenance] Change the inline assembly keyword to `_asm`
The single underscore version is actually slightly more supported among
the compilers I've seen so far. Also added the exact list now.

nmlgc efff8d61bb [Maintenance] Change line endings in old C/C++ files to LF
Yup, even a DOS compiler from 1994 considered CRLF line endings as
stupid.

nmlgc 6ffe87f35b [Decompilation] [th01] Konngara: Main function
Third longest function in all of PC-98 Touhou, and it's even more of a
copy-pasta than the patterns we've seen earlier. Certainly didn't feel
that long.

nmlgc 5afee78f33 [Decompilation] [th01] Konngara: Loading and entrance animation
It's script-like code, what can you say. Maybe minimally sloppy in some
places, but ultimately harmless.

Oh, the Siddhaṃ seed syllables are supposed to show up immediately, with
no delay between them? Good to know – clocking your emulator too low
tends to roll them down from the top of the screen, and does add a
noticeable delay between the individual images.

… Wait, but this means that ZUN could have *intended* this "effect".
Why else would he not only put those syllables into four individual
images, but also show them on the foreground VRAM page?

nmlgc 1c5ed4b06e [Maintenance] Copy <dos.h>'s 16-bit x86 Real Mode declarations to a new file
DOS is not the same thing as the underlying CPU, after all. A separate
file not only indicates to future port authors which parts of the code
are x86-specific, but it also speeds up build times…

… in theory, because removing 677 lines from 49 files each doesn't seem
to speed up the build as much as I had hoped? But apparently my whole
system mysteriously got faster in the meantime, and I was getting 22-23
seconds for the entire repo even before this commit. Good enough.

nmlgc 43c97ccaa1 [Maintenance] Decide on __asm as the keyword for inline assembly
Which works in both Borland C++, Open Watcom, and Visual C++.

Not that we're about to port any of the games to these compilers, just
something I noticed while evaluating 32-bit compilers for ReC98's own
32-bit pipeline tools. Modders might want to look into that though,
since 100% position independence also makes it easier to change
compilers.
