nmlgc a4a5bc9df9 [Reduction] #502: graph_gaiji_putc 
Introducing MASTERMOD v3. How long until a GAME_NUMBER macro? (Answer: Once we
find ZUN code that slightly changed between games.)

Yup, ZUN makes use of this structure. In combination with master.lib.

Which challenges a lot about what we thought to know about Amusement Makers'
modifications to master.lib, due to the fact that TH02 contains the modified
version of this function, but the original of draw_trapezoid...

And I haven't even begun to research how this removal of conditional branches
could have a positive effect on the game, especially since it's only called
before exiting anyway.

nmlgc 0d213f41b5 [Reduction] #484-485: resdata_exist and resdata_create 
Looks like the 'pal98 grb' string was merely copy-pasted from the respal
module and isn't actually used by the function, which means that we don't have
to work around a naming collision after all.

nmlgc 61a0a024e2 [Reduction] #483: dos_free 
OK. I'm going to spend one day on TH01 alone, and if that doesn't end up
shredding the code significantly, I'm not going to cover that game.

nmlgc 84b7d0f1ab [Reduction] #467: Far long multiplication 
Yeah, the code is identical to the near version, with the only difference
being the PROC directive declaring the function as either near or far. Now, I
could either turn the function body into some kind of macro stored in a
separate file and then instantiate it from both near and far functions... or I
could just copy the original structure. Who cares, anyway.

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...

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