; Duck Hunt (JUE) application-specific RAM aliases - Pass 1
|
|
; Generated from every direct zero-page operand in reachable code:
|
|
; ref counts are reads/writes, `where` lists the referencing addresses.
|
|
; ZpXX names indicate storage with a role not yet unique enough for a behavioral name;
|
|
; Pass 2 replaces them with names derived from observed usage.
|
|
; Semantic aliases (Pass 2) sit beside neutral ZpXX names.
