nmlgc 23aa61c002 [Reduction] #446: abort 
The one with the single underscore, which is just raise + a wrapper around the
one with two underscores.

nmlgc b82a03c3f8 [Reduction] #441: grcg_round_boxfill 
No local symbol definitions for variables here, as they are used in both 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...

nmlgc f994832a28 [Reduction] #431: toupper 
Neither is this one. Also, interesting how IDA didn't identify the function in
one third of the cases.

[Binary change] Order of 2 relocations in TH03's MAINL.EXE, TH04's MAIN.EXE
and MAINE.EXE, and TH05's MAINE.EXE.

... huh? That is certainly not multi-byte safe.

nmlgc c90b76bff9 [Reduction] #426: graph_200line 
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.

nmlgc b2c9ba67bc [Reduction] #422: draw_trapezoid 
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.

[Binary change] Order of 3 relocations in TH05's OP.EXE.
