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

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.

- 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

Closing as duplicate of #2037. This PR was created with a cleaner commit history but #2037 has already been reviewed and properly reverts the fn_800204C8 partial match and lb_8001C4A8 variable reordering that cause regressions.
