The one with the single underscore, which is just raise + a wrapper around the

normal function and the retfunc.

nmlgc 6250206235 [Reduction] #432-440: xxv.cpp 
OK, *that's* the last piece of C++ crud shared across all main executables.
According to the object in the library file though, it seems to include one
more dword named
	__DestructorCountPtr
in the BSS segment. Neither games nor the runtime itself seem to use it, and
as a consequence, it doesn't even seem to be included in the games' BSS
segments, given that they all end with the symbols of xx.cpp...

Neither is this one. Also, interesting how IDA didn't identify the function in
one third of the cases.

Yup. TH03's graphics layer is actually set to a resolution of 640x200 and
upscaled by the hardware, which gives the game its distinctive low-res look.

Yup. From TH03 on, ZUN uses a different version of master.lib, containing more
features than the last official version 0.23 from May 1995. Given the relative
insignificance of the features in question, I presume that Amusement Makers
must have kept their own, improved fork of master.lib, rather than ZUN having
hacked master.lib on his own.

Anyway, that doesn't matter. In the end, we still have to reverse-engineer each
and every one of these changes, and some of the more complicated functions
won't even be reduced before the actual reverse-engineering step of this
project.

God, this C++ stuff really is a crappy mess. Even had to manually adjust the
alignments at the end of the the TEXTC segment - and no, the ALIGN directive
remains an inadequate tool random bytes, even more so because TASM's
implementation just pads the space with random bytes. But hey, nice to finally
see some reduction outside of seg000.

Well. Even after downloading pretty much every (identical) copy of Turbo /
Borland C++ 3, 4, 5 and everything inbetween, I could *not* find the original
source to most of the C++ parts in the runtime. Using the IDA disassemblies
to build their slices is simply the only option.

nmlgc a9918e364e [Reduction] #259: C++ delete[] operator 
Same for registerbgifont() being a wrapper around registerfarbgifont(). But
at least there, IDA should have noticed something weird. The original delete[]
operator refers to the delete function, so registerbgifont() would have had to
be a wrapper around registerbgidriver(), which of course doesn't make sense,
and IDA claims to *know* these functions...

nmlgc 0493c0c4e4 [Reduction] #258: C++ delete operator 
Lol, "registerbgidriver". Just because the original function is nothing but a
wrapper around free(), and registerbgidriver() is also just a wrapper around
registerfarbgidriver().

support segment prefixes in EQU directives?

And yes, there really is no viable solution for both the NOPCALL problem (the
TASM manual states that these NOPs are inserted during single-pass assembly,
which we can't do) and the complementary jump sequences (which are only
inserted for forward references when specifying the JUMPS directive, which
doesn't seem to work for us either).
