Cool demo. Only watched it on video (no ste) but your overscan code's pretty impressive. Is the mountain calculated in synchronized code? Or do you just render it there, and calculate it in the non-overscan part:
FWIW, overscan without stabilizer is a really old technique... My first overscan routines didn't have it and were unstable to my disappointment. Stabilizers were the missing puzzle piece to make overscan work on vanilla ST's. It's like fashions... the old thing is now the new new thing :-) Interesting that STE's don't need it. I remember than DOM's "official" Atari ST demo (paid for by Atari IIRC) had overscan (and Krazy Rex's picture) -- do you know if he used a stabilizer?
Also I take it that there are no DMA conflicts for memory access between fetching the digital sound and overscan? On the ST, if you read from the floppy while in overscan, your code fetches would be delayed by the floppy DMA -- causing the overscan to flake out?

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
