; There is room for further size-optimizations. Look at the crinkler_report.html to try and find ways to reduce the final size.
; Try to do anything differently. Inline vs. function call? mov vs. push/pop combinations? different orderings for push/pop if you can?
; Try un-defining SLEEP_TO_LET_MUSIC_THREAD_GET_A_HEAD_START.
; Remove the safety padding at the end of the DEVMODE struct.
