With the tutorials available, I learned how to do a synchronous fullscreen (the one with lots of nops that can be filled with more useful code).
In http://codercorner.com/fullscrn.txt however, Flix mentions a new, unsynchronous method (look in the last two or three paragraphs). Does anybody know, how it works? (or isn't it possible at all and that part of the text is a hoax?)
Thanks in advance,
Here is, what Flix wrote in http://codercorner.com/fullscrn.txt :
A few days after the ICC #2 I developed a new fullscreen-
routine. With this routine the main program does not have to be
synchronous with the electron-ray. The disadvantage of this
method is that the border annihilation takes up to 50 per cent
of the processor time. Therefore you can use keyboard-requests,
multiplications, divisions and interrupts. The routine is,
allthough it's awfully old, top secret and cannot be published
in Maggie (yet).
