* {{$|0E30}}[{{0x|10}}] = Subtype designation 1
Is formed as follows: Take bits 5 and 6 from the sprite's Y coordinate byte and shift right twice.
Then take bits 5, 6, and 7 from the X coordinate byte and shift right five times. This produces 000yyxxx.
The bottom three bits cannot all be set at the same time or else we'll have an overlord instead.
So if that wasn't the case we'd have 32 possible subtypes, but in lieu of the extra rule,
7, 15, 23, and 31 cannot be used.
A safe way to use this would be to just not use the bottom bit. (allows 16 subtypes)
* {{$|0E40}}[{{0x|10}}] = Bits 0-4: If zero, the sprite is invisible. Otherwise, visible.
(actually, it seems like this is the number of OAM sprite slots allocated to this sprite object)
Bit 5: Causes enemies to go towards the walls? strange...

Bit 7: If set, enemy is harmless. Otherwise you take damage from contact.
* {{$|0E50}}[{{0x|10}}] = Sprite HP
* {{$|0E60}}[{{0x|10}}] = Bit 4: If set, draw a shadow for the sprite when doing OAM handling

Also applies to sprites and perhaps other similar types of objects.

the current low byte of the h count (ppu) plus the frame index ($1a) is added to this variable

a debug or "cheat" variable. When the value is odd, the game is frozen. The sprites that are on screen
will stay on screen.

* {{$|0FFA}}[{{0x|01}}] = When a screen transition occurs in the overworld or indoors,
this is set to the value of the variable $1B
Sprites are cached and reloaded from adjacent rooms only indoors,
so this serves the purpose of letting the game know to not reload
cached sprites during a screen transition.
