That should make this convoluted copypasta a bit easier to read. And
sure, I could have done something about the loop as well, but
SHOT_FUNC_INIT already hides enough control flow behind a macro…

The TH05 difference: A ridiculous out-of-bounds structure field access.
Could have done safely by just passing a shot_t*, but ZUN's too cool
for that?
Also, about time we started putting the function prototypes directly
into the C headers, and the C headers *only*, upon reverse-engineering…

It seems that the main th0?/ directories should only contain actual
translation units (of which there are more than previously assumed)
as well as other not really further classifiable slices?

And once again, the TH05 version is un-decompilable. :/ It was pretty
close this time, though, as the entire block between PUSH DI and POP DI
kind of resembles a separate inlined function, in accordance with Turbo
C++'s automatic backup of the DI register, as researched in 7f971a0.
Except that it contains a loop, and Turbo C++ refuses to inline any
function with `do`, `while`, `for`, or `goto`. If it didn't, it would
have totally worked.
Also, yes, C++ class methods are treated identically in this regard.
Oh well. Shot type control functions next, finally!

Including the confirmation that both games have an 8-frame deathbomb
window.
The placement of the variables is all over the place though, what the
hell?

They are supposed to lag behind the player's movement by one frame, and
therefore have to be tracked separately.
I would have also included TH02, if it weren't for the weird sprite
indirection system (not storing X and Y positions directly in the
structure, but taking them from a buffer, with their addresses
always changing, WTF?!) that absolutely needs separate attention.
