"Black Sabbath" is a Plus demo by BDC-Iron released in 2001.
This demo is for the Plus only. Technically this demo shows for the first time hardware sprites repeated on line-splitscreens to display bars in the middle.
At the top, the three transparent spheres (made of hardware sprites) are moving on split-rasters.
- Was briefly (at least 2 seconds) displayed at Alchimie 2017 as a screen-test on the main projector-screen for the following competing Amstrad GX4000/PLUS productions.
