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.
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.
