I could care less about Mac II's right now, all I want to do is REALLY FAST animation of a bunch of objects and even screen scrolling! That's all! If I wanted to be upwardly compatible and all, I wouldn't be writing directly to the memory! Copybits sure is versatile, but I need pure 68K turbocharging!! Dark Castle (and beyond DC) both use screen swapping ( you can see the effect by having the Jclock init while the screen is scrolling in the labyrinths, it's all over the place)... Does these games work on a Mac II? Ben -- bm1q@andrew.cmu.edu
