Partially match fn_800204C8 in lbbgflash.c with 91.9% match.
Remaining differences are branch structure (bge+b vs inverted blt).

Subject: [PATCH 04/12] Fix build: revert lbrefract.c to NonMatching
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous commit incorrectly set lbrefract.c to Matching, but
the file is missing stub markers for unimplemented functions
(lbRefract_800222A4, lbRefract_80022560, etc.), causing linker errors.

Subject: [PATCH 09/12] Revert fn_800204C8 to stub (partial match causing link
 failure)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 91.9% match was causing symbol shift in the linked binary.
Reverted to stub for now - can be fixed by /decomp-fixup later.

- Change lbAudioAx_800265C4 return type from int to bool
- Use M2C_FIELD macro for raw field access
- Use true/false instead of 1/0 for bool returns
