nmlgc da6b856dc5 [Reverse-engineering] [th04/th05] Stage enemy structure 
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.

nmlgc ba66fcc801 [Reverse-engineering] [th04/th05] Currently alive player shots 
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.

nmlgc 117fa02525 [Reverse-engineering] [th04] Stage 6 Yuuka's parasol and vanishing animations 
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…

nmlgc 65816a43db [Reverse-engineering] [th02/th04/th05] Pellet rendering 
… 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.

nmlgc 4843d17aae [Reverse-engineering] [th02/th04/th05] Hardcoded 8×8 pellet sprites 
The bottom gray part of pellets in TH04 and TH05 is actually a separate
8×4 sprite…

nmlgc eb0cf6820f [Reverse-engineering] [th04/th05] Bullet-related sprite IDs 
IDs based on Maribel Hearn's jargon page
(https://maribelhearn.com/jargon) as well as Sparen's Danmaku Design
Guide (https://sparen.github.io/ph3tutorials/ddsga1.html#sub2).

nmlgc d6f356da45 [Maintenance] Use a single per-game, per-binary file for super_*() patnum IDs 
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.
