Hello there. This time we will scroll two chessboards at the same time with different speeds. This is somewhat similar to a parallax effect. BASIC 2.0 is used for this.
The code is not difficult and it has been obtained by applying slight modifications to the previous scrolling chessboard program.
Some flicker do happen, but the code is more for clarity rather than for speed. Better results may be achieved by using PRINT instead of POKE to store values on memory, but this technique is quite complicated.
Have fun with the Commodore 64!
