"... at the end of which -me- from the exceptions will explain how to use border-scrolling techniques!!"
How many times did I read the whole scrolling of the BIG demo ? Seeing the walls scrolling after that, just to be able to reach the part of the scroll where the 60/50 Hz switch was explained, quickly taking note on a paper. And how many hours did I watch the Little Color Demo in 1988, stunned by the colors on the screen and the way it pushed the "normal" specs of the Atari ST ? Even watching it today brings me 28 years back in time with the same feelings.
Sad news, certainly one of the pionners of the ST demo history, who motivated so much people to code harder and push the ST, we owe him a lot !
