A toolkit which easily allows you to create parallax HDMA on either layer 1, 2 or 3.
Unlike most parallax HDMA, this one is more generalised and you can scroll the affected layer vertically. You can also enable waves on certain lines.
Tested with: Lunar Magic 3.11, UberASM Tool 1.4, SA-1 1.32, Snes9x 1.60.
Very nice toolkit and pretty simple to use. Be sure to read the readme as it explains pretty much everything and it provides answers to some issues you might encounter when using it.
