List of Hardcoded Subs in Rhythm Heaven Megamix

Below is a list of hardcoded subs in Rhythm Heaven Megamix, and what they do.

For the tickflow code of every sub, see this document. Synchronous subs end with return. Asynchronous subs end with stop. Call synchronous subs with sub. Call asynchronous subs with async_sub.

0x0
Constantly checks if a textbox is on screen. If there’s a textbox, pause tickflow execution until the textbox goes away.

0x1
Possibly checks if .aac (the music file) is fully loaded and ready to be played? If not, pause tickflow

0x2
Possibly checks if .bcgrp (the sfx file) is fully loaded and ready to be played back? If not, pause tickflow

0x3
Pauses tickflow until all sfx is loaded properly

0x4
Used in Remix transitions to keep it on beat (scene loading can and will make tickflow execution offbeat from the music without this)
