nmlgc ffcc46d32f [Decompilation] [th05] pi_put_8(), pi_put_quarter_8()
> assigning to the DI register immediately before a CALL
Yeah, no amount of comma operator trickery can get *that* out of this
compiler. Also, these TH05 .PI functions are the only place in PC-98
Touhou with a `IMUL DI, imm8` instruction, which is impossible to get
out of Turbo C++'s built-in assembler.
Well, at least the `if` branches decompile somewhat nicely.

nmlgc 25d26824a1 [Separate translation units] [th05] pi_palette_apply() (undecompilable)
… especially because this one *is* actually undecompilable. Reason:
Base pointer assignment to BX, before saving the SI register on the
stack.

nmlgc 2777bae55b [Separate translation units] [th05] pi_free() (undecompilable)
Well, it *would* have been decompilable, but that ridiculous placement
of the nullptr assignment would have forced the entire function call to
be spelled out in inline ASM, verbatim. No amount of comma operator
trickery would have generated the same instructions either. And for a
function this small and obvious in what its decompilation *should* be,
it really defeated the purpose of adding a separate translation unit…
