With TH04's version hardcoding not only Gengetsu's dialog and
initialization, but also the Bad Ending after having clearing Stage 5
with continues or on Easy difficulty.

Aha! TH05 actually loads every single rendered dialog image
individually before rendering it, either from the EMS area or disk.
That's one way to save memory, I guess?

Oh, an EMS function that does one single thing, and is not potentially
bugged within TH05's original sprite limits?! (Although that last part
might have just been a happy accident.)

No, I'm not copying exactly what was on ZUN's monitor during the 2010
MAG・ネット documentary. Also, this one was very lucky not to receive
a stupid function name.

… (24 + (difficulty * 8) + rank) in TH04, and (42 + (difficulty * 8))
in TH05. Also, TH05 only doesn't have TH04's bullet zap animation
because ZUN didn't consistently use constants…

And actually document them correctly.
Clear: Custom duration, awards constant points per bullet during the
entire duration, plays a decay animation
Zap: Fixed duration, awards a semi-exponential bonus for all bullets
alive on the first frame, plays a, um, "zapping" animation… in
TH04, because it's bugged in TH05 :zunpet:

64 slots reserved, 16 slots actually used, another 768 bytes of
conventional RAM wasted…
(And yes, that naming convention is indeed meant as a shoutout to all
the RPG Maker veterans out there.)

Right, because you'd also want to automatically shift the IDs for every
stage-specific sprite if you add or remove a new stage-independent one.

A future sprite converter (documented in #8) could then convert these
to C or ASM arrays.
(Except for the piano sprites for TH05's Music Room, which are stored
and used in such a compressed way that it defeats the purpose of
storing them as bitmaps.
Last one of the shared entity types! The TH05 version of the .STD enemy
VM would now be ready for decompilation in one single future push.

Copying out the shot position might have actually been a decent
optimization for hit detection, to avoid the indirection if the shot
is not colliding with anything.

Yes, this is the best time to cover these, since Stage 6 Yuuka's
animation state is reset in a variety of the boss phase end functions…

… which allows a split into first rendering the top part of every
pellet, then the bottom part. This way, the game only needs two
grcg_setcolor() calls for any number of pellets.

Since they're determined by the order of sprites in a .BFT file,
they're best auto-generated by an enum as much as possible.
