[Reverse-engineering] [th05] Micro-optimized monochrome 16×16 sprite display Might as well cover this one while I've got this type of function in my head. This one is used for the animated star backgrounds during Stage 2 and the Shinki battle. Completes P0073, funded by [Anonymous] and -Tom-.

#include "th04/formats/super.h"
// Displays the alpha plane of the (non-tiny!) 16x16 sprite with the given
// [patnum] using the current GRCG tile/color.
#define z_super_roll_put_16x16_mono(left, top, patnum) \
_AX = top; \
_CX = left; \
z_super_roll_put_16x16_mono_raw(patnum);
[Decompilation] [th05] Shinki: Background particle rendering We really wouldn't have wanted to start writing inline ASM in the middle of a conditional expression just to get that janky `CMP AX, 0` instead of TCC's sensible `OR AX, AX` optimization. Part of P0146, funded by -Tom- and Ember2528.
