  Shifter Distortions
Sun 18th October 2020   
A few days ago, I saw on Twitter an interesting link to an article from Mark Wrobel explaining how the classic horizontal distortion effect was done on the Amiga computer using the copper, complete with some source code and pictures to explain it all.

Size coding is an interesting challenge: After spending a day at work using a computer that counts memory in gigabytes and storage in terabytes, it's refreshing to go back to basics.

Back in the days, people HAD to write compact and efficient code, simply because the hardware would not allow for anything else.

These days it's more like an intellectual puzzle game, which I find deeply satisfying.

  Shadow of the Beast
Sat 12th October 2019   
Now and then somebody speaks of the "game" Shadow of the Beast and uses it as an example of something the Amiga range of computers could do but the Atari ST could never dream to achieve.

This is totally true: Even with all the time and talent of the universe, there is no way a standard Atari 520 ST could compete, in what is after all mostly a technical demo designed to exploit every single feature the Amiga had.

The actual point of contention is regarding if the Atari ST port of Shadow of the Beast was as good as it could possibly have been considering the usual constraints of time, budget, etc...

  Reverse engineering

Thanks to a correct alignment of planets I ended up with a four days long weekend.

I had plenty of things to do, but I decided instead to spend the time looking at how one of my favorite Atari demo screens was done.
