VSP = HSP and HSP (Linecrunching) = VSP
I don't know what scene genius decided that VERTICAL SCREEN POSITIONING should describe the effect of moving the screen HORIZONTALLY (and vice versa with HSP/Linecrunching) but it's been bugging me like forever... Isn't it about time we used the correct terminology?
Discuss! 8)
P.S: In Crest, we barely ever called it VSP and HSP, Crossbow just calls the effects "Wanker" (yes, seriously, from german "wanken", meaning to sway left & right - our english wasn't all that great back then!) and "Linecruncher"! ;-) |

Quote: I mean, I called VSP "Johnscroll" for years, because my first exposure came from being in the same room when John West (of 64doc) independently stumbled across the effect.
(this was in early 1989, but neither of us were aware of prior art at the time - we were just "why the fuck has this raster routine we're running in the background confused BASIC into putting the starts of lines halfway across the screen???")
Yeah, I also stumbled across it by chance when I was hacking around in Cosmos' AFLI displayer and suddenly the whole screen was shifted! ;-) |

Quote: Quoting iAN CooGSeems like you are creating the problem yourselves. Whoever wrote the V stands for Vertical is wrong, just ignore the error and while at it, fix the wikipedia if it bothers you so much. Indeed, Wikipedia is worth shit for C-64 stuff. And so is Reddit. And yes, scene terminology was always shit, too. =)
No need to fix it - cause it's correct, it quotes VSP as vertical screen positioning and HSP as horizontal! ;-) |

"Wanker" is a term invented by "64er", btw - and it means something different - generally moving a logo (or GFX) left and right - not necessarily using DMA-delay (which is the proper term) :)
(also FLI is "Flexible Line Interpretation", not "Interpreter")
Wow, I did not know that... Sure that 64'er didn't just get it from Crest demos? 8)
P.S: Wasn't a swinging logo also called "TicToc" at some point? |

Quoting DeeKayWasn't a swinging logo also called "TicToc" at some point? You're probably referring to "tech-tech", which originated with https://www.pouet.net/prod.php?which=4445 and refers to being able to move lines horizontally independently from each other. A step up from "wanker". =) |

Err - no, I wasn't. And thanks for the eggsplanation what TechTech is, I totally didn't know! >:-) |

Don't we all remember what a rabbit hole trying to fix Wikipedia can be...? :) |

It was 64'er - Hannes Sommer would be my guess (who often came up with this kind of articles).
I also remember "Tic Toc" being "Tech Tech"... no idea where i have seen that used though.

It's about as "correct" as FLI being "Funky Loud Intermediates" :)
Is that "Rasterzeileninterrupt" dude still active? Perhaps he can fix it! |

Quote: But nobody calls it "Variable". Not even Wikiedia does (which has it the right way around btw! ;-)
Also, "HSP" would still not make sense..

Didn't it originate from this demo? VSP&IK+
Oh, [edit] Ian already mentioned it, the source :) |

For a long time i thought that VSP stands for 'Variable Screen Position'.
But it make also sense that VSP means 'Vertical Screen Position' and HSP 'Horizontal Screen Position' aka Linecrunshing.
Together, VSP + HSP = AGSP (Any Given Screen Position).
But anyway, great stuff! |

Apparently Ivo Herzeg (aka Mr.Cursor) used "VSP" and "HSP" in the Magic Disk Articles: https://dmhas.de/site/downloads/IRQ-Kurs_Magic_Disk.pdf - that explains the confusion. Kinda weird to not at least clear it up, years after the term was established. |
