nmlgc 4dc9b9ab4a [JWasm move] Don't use the DIST/CALLMODEL constants for procedures and labels 
Once you've actually found the right syntax that makes the assembler just use
the default call type of the current memory model for both procedures (where
it's just "PROC" without anything else) and labels (where it's "LABEL PROC"),
these constants become completely unneccessary, even with TASM.

nmlgc 340c8a792a General cleanup 
Mostly moving spurious null bytes, which are actually supposed to denote
alignment, into their associated slices, but also prettying up some of the
very first slices.

nmlgc 274b37eed7 [Reduction] #504: master.lib version string 
Fulfilling the original licensing conditions... I think.

Introducing MASTERMOD v3. How long until a GAME_NUMBER macro? (Answer: Once we
find ZUN code that slightly changed between games.)

nmlgc 80fc5c6d82 [Reduction] #496: mem_unassign 
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.

No local symbol definitions for variables here, as they are used in both the
normal function and the retfunc.

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.
