The Confusion Demo screen written by Bruno Azzara of GBP Software. This screen was written for the Hysteria Demo and features a 32×32 single plane horizontal scroller, a single plane vertical scrolling background, multiple parallax, a vertical scroller and vu-meters.
Included in the zip file is the full source code for the screen.
Neil started coding in STOS in 1989 just after it was released in the UK.
During those 31 years he has written numerous demo screens, routines, games and extensions, most of which are now lost due to a massive hard disk crash. What remains on floppy disk is still being discovered and posted on the STOS Coders website and stored in the cloud for everybody to enjoy (or laugh at).
Neil is the author of the GBP Extension which added some pretty cool commands to STOS, along with the "Development" extension that enabled enhanced STE functionality, including probably one of the simplest hardware scrolling routines around.
Along with Bruno Azzara, Geoff Harrison and Mike Halliday we had loads of fun back in the day trying to push STOS to it's limits. We are all now enjoying bringing our knowledge to a new generation of STOS Coders.
