+ * func_800475CC — 116 bytes at 0x800475CC..0x80047640
+ *
+ * Copies two unsigned halfwords from the pair referenced at a1+0x0C and one
+ * unsigned halfword from the pair referenced at a1+0x10 into a three-halfword
+ * stack temporary. The three values are sign-extended into consecutive output
+ * words at a2, and the function returns whether the second value is not -32768.
+ *
+ * The repeated a1+0x0C expressions are intentional: the target reloads the first
+ * pair pointer for its two fields. The local halfword array supplies the 8-byte
+ * frame and the target's raw stack stores without inventing a larger record type.
+ *
+ * LIMITS: the pair and output meanings are not inferred. The input pointer
+ * offsets 0x0C/0x10, field widths, stack offsets, sign extensions, sentinel
+ * comparison, and return are byte evidence.
