To be true this intro was a kind of result from the Lotus game StingRay did. As this cracktro in front of the game was quite small he tricked around to make the original tune possible in 4kb and finished that nice oldschool thing. This intro is coded using the old kind of coding style and as a little bonus the complete source code is included in the archive.
Just a one screen effect, but well, that was how the original cracktro looked like. :) Sine scroller and some text and some chip music.
