/ 4K 4-BITS MEGA SCROLLER, by DYNO SILLY VENTURE 2K17 \
'-------------------------------------------------------------------'
: :
: Dyno proudly presents his contribution to the SillyVenture demo :
: party that took place in Gdansk (Poland) on december 9th 2017 :
: :
: This is a Mega Scroller in just four kilobyte, using the 4-bits :
: hardscroll technique created by Alien/ST Connexion. :
: :
: The demo works on Atari STF with 512k RAM. :
: :
: It also works on STE/Mega STE, using native scroll features :
: (hscroll register without prefetch) at the expense of a black :
: border added on the left of the screen :
: :
: I had inspiration for this screen watching the hidden screen by :
: the Black Cats on the Vodka demo by Equinox, with its nice and :
: polished font. :
: :
: To fit into 4kb, the demo is compressed with the amazing :
: Shrinkler packer, by Blueberry/Loonies. :
: :
: The commented source code is attached if anyone is interested. :

/ SPECIAL THANKS \
'-------------------------------------------------------------------'
: :
: I would like to send a special thanks to Alien/ST Connexion :
: who did a series of articles about overscan in ST Magazine, a :
: french publication (that were partially translated in Alive :
: diskmag 9 & 11), and where he explained the 4-bits hardscroll :
: technique in detail, in ST Magazine 55 from october 1991... :
: :
: This article (like the previous ones !) have been a great :
: source of inspiration when coding this screen. For all these :
: brilliant articles, thank you very much Alien, you have my :
: eternal gratitude ! :
