Massively Interleaved Sprite Crunch

I wrote a technical description of one of the new effects in Lunatico: Massively Interleaved Sprite Crunch (MISC).

Enjoy!

thanks for the article, master LFT! I'll read and read again your article till I will understand something! :)
just a question: did u have some cyles left in that part, like extending the effect in the upper or lower border could have be done?

@LFT: I do agree with the statement you make at the end of that article!

Great article, and some very neat tricks. Thanks!

ZeSmasher: I guess extending to upper/lower borders would be hard, as you'd have to use the ghost byte to trigger scheduling, and those would cover all 3 bytes of every sprite row.

Thanx, much appreciated! I had no idea, sprite crunching was this complicated. Very impressive work.

Very nice. I love the sprite collision register is used to fast calculate the sprite crunch. Thats brilliant!

Agreed, very nice use of the collisions to encode the y expand values.

This is some interesting stuff!
Although, I have to admit that my experience reading the article ended up a bit like this...

Heh, ending with a naughty book flip? The passion.

Honestly, too complicated for me to implement too, but Linus's articles are very educational and interestingly written. I'm sure we'll see other implementations using the same techniques, but with a different approach and visual outcome. We, the spectators, will benefit too.
