Here's an optimization tip if you're used to programming in C: On the 65xx it is faster to convert an array of structures to a structure of arrays.

That means if you want to have an array of 16-bit integers, convert it into an array of high bytes and an array of low bytes. The reason this is faster is that you don't have to scale the array index or use indexed indirect addressing for most purposes.

Well, it's nothing worth mentioning actually. The last one was "Ledge and Deary" from the Solskogen party

You're too modest skurk - number one at Solskogen '08 and nothing worth mentioning?! And now, as well as that honour, you can also claim that pmc once saw it and thought: that three dee twisty scroller thing was cool.

I'm working on another multipart demo, but I'm not sure when/where it will be released yet.

Looking forward to it already.
