Wheee, my first "decent" effect. IE, the first one that actually worked. Yay HDMA!
This effect writes to the screen brightness value on a per scanline basis. Of course the per scanline part goes without saying because what else would I use HDMA for.

Fun with the mosiac effect! The effect it's self can be done layer by layer depending on the bits you set. It looks really trippy when the screen is scrolling.
I was somewhat surprised this could be done on a scanline basis.

First attempt at a background gradient. I could possible find a way to stop it from showing through Layer 2. I tried CGADSUB, and every variant of color math you could imagine.
...Then I learned you couldn't use the register I was using to write BG colors. (Thanks Smalls)

Then I finally got the result I wanted! I pretty cool color gradient, I did from scratch with just LevelASM. Pretty neat huh? Took long enough... and I can't imagine how hard it would be to set up wavy effects and scrolling effects. There's a reason people make kits for this.
If this looks like crap... it's because Blogger is dumb with images. Probably won't look good on a larger/smaller resolution than mine.
