VWF Text Format

Values 0x00-0x1F are reserved for special commands, 0x20 is reserved for a space, and the rest refer to normal characters.

The special command values behave as follows:

$00 - End message

$01,$xx - Wait XX frames

$02 - New line

$03,$xx,$yy -

$04,$xx - ???
Next byte is written to $7E0069.

$05,$xx - Set character width, in pixels
If xx is FF, the text will use a dynamic width instead.

$06,$xx,$yy - ???
Stores #$xx to $005B and #$yy to $005D.

$07 : dw $BBAA - ???
Stores #$BBAA to $005F.

$08,$xx - Change text color
Writes XX to the text color settings; format: ----bbff
ff - Foreground text color.
bb - Background text color.

$09,$xx -

$0A - Disable ???
$0B - Enable ???
Toggles $0066.

$0C,$xx,$yy - ???

$0D,$xx - ???

$0E : dl $CCBBAA - Jump to text macro
Changes the text pointer to $CCBBAA. When the end of that text is reached, returns back to the byte after this command.

$0F : dl $CCBBAA -
Not really sure what this is doing, among other things it changes the text pointer to 0077.

$10 : dl $CCBBAA : db $DD - Write 8-bit value to RAM address
Writes #$DD to the RAM address at $CCBBAA.

$11 : dl $CCBBAA : dw $EEDD - Write 16-bit value to RAM address
