Hardware latch behaviour
There are two hardware latches: one controls the cartridge icon, while the other controls the sound icons. These latches are always displayed for an additional 128 ticks after their display condition stops being true.
Sound icons
The volume and headphone icon are enabled when pressing the SOUND button, according to this algorithm:
- If headphones are plugged in, show the Headphone icon.
- If headphones are not plugged in, show the Speaker icon and the following Volume icons:
- Volume level 0: None
- Volume level 1: A
- Volume level 2: B
- Volume level 3: A, B
TODO: This documents the WonderSwan Color. The specifics probably work differently on the mono WonderSwan.
Cartridge icon
The cartridge icon is displayed for 128 ticks after the System Control cartridge test passes on console start.
