GUIDE

Controls

Button	Does
Up	Wave on, then taller — press again for more (3 levels)
Down	Wave off, back to straight
Left / Right	Scroll forward / reverse
A	Flip text between Text and Text alt colours
B	Scroll speed
Select	Character size (small / large)
Start	Next character set (4 of them)

Size, character set and speed change when the message next loops — the ROM only alters them at a safe point so the scroll never tears.

Colours

Slot	Does
Background	Screen background. The shading blocks at the screen edges follow this colour so they stay hidden.
Text	Main font colour.
Text alt (A)	Second font colour, reached with the A button. Set it to something different or A will look broken.
Highlight	Only the last two character sets use this.

The NES palette has several near-identical whites — $20 and $30 are the same colour. If two slots look the same on screen, that is why.

Changelog

Remix — DOT.AY

Browser editor — set the message and all four palette colours, download a ready ROM. No assembler needed.
Wave mode — Up/Down bend the scroll into a sine wave at three amplitudes. Whole letters stay intact and words ride at different heights.
Reverse scrolling — Left and Right change direction on the fly.
Switchable text colour — A flips between two palette slots. Held down it strobes.
Full-height edge masks — the shading blocks now cover the whole screen, so waving text is hidden properly as it enters and leaves.
Background colour is editable — it was previously locked to black by a palette mirroring quirk, and the edge shading now follows it.
