more mad - rotating zooming chessboard

Post by simon »

I was playing with rotations on a coco 3 and decided to cook a little SG version for you all....

rotating zooming chessboard...

enjoy

you would do well to hard reset the machine after running it if your using DOS, as the screen area is a little unsafe ($400..$c00)
