Following on from both Old School Demos 1 & 2 comes 'Old School Demo III', released by Cosine.

The demo can be downloaded from the Cosine website...
http://www.cosine.org.uk/products.php?prod=old_school_demo_3&4mat=pcThe demo is 'interactive'. At the start, all sprites are switched off and certain keypresses will switch sprites on. Also, there is a hidden part activated with a certain other keypress...
All code, graphics and music is by me. The moon image came from a little organisation called NASA

Included in the download archive is the PureBasic source and all the graphic and music files in their original formats. What's new for me coding wise? A vertical scroller, extensive use of transparencies, keyboard control, scanline emulation and further refinement of my design and coding techniques. More info is in the scroller.
Tools used for this demo: PureBasic 5.60, Photoshop 7.0, MS Paint, Promotion 4.5, Crimson Editor, OpenMPT 1.27, Amiga ST-XX sample disk images.
