World Firsts and Records

Researched and documented by Jazzcat.

Welcome to the most extensive list of C64 demo scene World Firsts and World Records. This World of Demos segment is based on the original list of world firsts located on the very informative http://codebase64.org. The Recollection list of World Firsts and Records has already become the epicentre of demo achievement and will continue to be expanded and refined together with the assistance of the sceners directly involved.

Of course there will be many things missing from here and it does not have to be just demos, games had effects too! If you notice anything strange or have any additional reaction and can back it up with hard facts, please give me an email: jazzcat@nospam.c64.org

World Firsts - Effects

AGSP (Any Given Screen Position)

Definition: AGSP is the combination of Variable Screen Positioning (VSP) and Line Cruncher (making it possible to have games with colourful bitmap graphics that scrolled, such as Hannes Sommer's "Fred's Back" series).

Exilon/Microsystems Digital Technologies - 6 November 1988

AGSP (Any Given Screen Position) Flexible Line Interpretation (FLI)

Definition: AGSP is the combination of Variable Screen Positioning (VSP) and Line Crunching. In this effect, it is using the FLI mode.

Boogaloo/Horizon, Exilon/Horizon & Magic Man/Crazy - October 1990

Bitmap Stretcher

Definition: stretching a logo or picture (meaning just that, not turning it upside down or other things covered by FPP).

Bitbuster/Rawhead - 8 October 1988

Different Y Character Position (DYCP)

Yip/PureByte - 27 June 1986

Different Y Sideborder Position (DYSP)

Dosman/Triton Technology - January 1988

Flexible Line Distance (FLD)

Definition: moved bitmap or character rows an arbitrary number of vertical raster lines apart, making it possible to arbitrarily move any 8 pixel high graphic block smoothly up and down across the screen. Adding sine curves to this positioning provided a wavy effect.

R2D2/Flying Crackers - February 1986

Flexible Line Interpretation (FLI) (as moving colour effect)

Definition: FLI can be used to increase the number of unique colours which can appear in an 8x8 or 8x4 block on the screen. This mode is occasionally extended further with sprites and/or interlacing two bitmaps together (as in SHIFLI or UIFLI).

Solomon/Beyond Force - January 1989

FLI Changing DYCP (FCD)

Definition: soon.

Depeh/Antic - May 1991

Flexible Line Interpretation (FLI) Flexible Pixel Distance (FPD)

Definition: soon.

Crossbow/Crest - October 1990

Flexible Line Interpretation (FLI) Stretcher

Definition: one FLI line is stretched on the Y axis.

Trivia: does not have the graphical ability of the Crest routine but is the first of its kind.

ChristopherJam - 12 March 1991

Flexible Line Interpretation (FLI) Single Line Stretcher

Definition: one FLI line is stretched on the Y axis.

Crossbow/Crest - 26 April 1997

Flexible Pixel Position (FPP)

Definition: FPP is basically a variation of the FLI mode, allows the placement of any line of a character-based graphic at any one y-position, allowing for effects like x-rotating logos, barrel-like effects or smooth stretching and waving over the whole screen.

Crossbow/Crest - 20 April 1989

Interlaced Flexible Line Interpretation (IFLI) Line Crunching

Definition: soon.

Crossbow/Crest - 7 April 1996

Interlaced Flexible Line Interpretation (IFLI) Stretching (every 8th line)

Definition: soon.

Crossbow/Crest - 7 April 1996

Kefren Bars

Definition: soon.

Glasnost/Camelot - 28 December 1991

Line Crunching

Definition: The routine can scroll a bitmap larger than one screen vertically without having to move all the bitmap data manually.

The Omega Man/Teeside Cracking Service - 22 July 1987

Raytracing - Realtime

Depeh/Antic - 20 April 1992

Rotozoomer - Tilter

Perff/No Name - 29 December 1995

Side Borders

Definition: border restriction area around the screen, which works as a frame for the display area.

TSI/1001 Crew - April 1986

Sprite Crunching

Definition: Sprite Crunching is a way to shrink sprites in y-size, it is based on a glitch in the VIC-chip (which is quite common) that appears on a cycle-exact position every rasterline.

Crossbow/Crest - April 1997

Sprite Stretching

Definition: this VIC trick is about being able to stretch a horizontal line by any amount.

Bob/Triad - 26 February 1989

Tech Tech

Definition: this effect assigns a new X-position to any line of a graphic. By using animated sine waves the routine could for example wave a logo or picture horizontally over the screen.

Omega Supreme & Moonray/Rawhead/The Shadows - 13 June 1988

Twister (diagonal)

Definition: diagonal (45 degree) precalculated slices

Britelite/Dekadence - 12 April 2009

Twister (horizontal)

Definition: twister made with character-precision horizontally with a precalculated charset.

Britelite/Dekadence - 26 March 2005

Twister (horizontal)

Definition: twister made with pixel-precision horizontally.

Britelite/Dekadence - 20 September 2005

Upper/Lower Borders

Definition: border restriction area around the screen, which works as a frame for the display area.

Flash/Flash Cracking Group - 11 October 1985

Variable Screen Positioning (VSP)

Definition: allows arbitrary x-placement of a bitmap, with the bitmap wrapping around at the border.
