I always was under the impression that both vertical + horizontal was linecrunching. At least that's what we called it back in the day ..
ehehe indeed :=) for me, it was ivo herzeg who cleared that up for me (and thus i am familiar with his terms, not the older "variable screen position") |

Yeah! In the 80's and 90's noone knew what they were talking about, and also didn't understand what they were inventing -> giving totally confusing names to things.
..but now we have internet!! And stuff like CSDb, so now everyone can understand.. If we just could explain what people didn't understand before, and do it right now once and for all. If people just stopped talking so much crap all the time, we could instead focus on getting things right, and explain all those things that were confusing back then.. Ok, are you with me!??! before they had vsp, hires scroll and sometimes linecrunching. But now, we have vsp and hsp, and also agpsp and bitmap, but the old stuff is still there.. cause it's really the same, right.. just different name. ..and sometimes even same name for different things.. Uuuhh. ..but we have internet now, so everyone should really be able to understand.. Yepp.
Well, that's just my 50 cents. Maybe someone else can fill me in. |

i remember discussing vsp with ruffian way back in the day and we didn't even know it had a name. our definition was "fuck around with $d011 and make the screen shift"... |

No, you made it perfectly clear for me! Just fuck around with d011 a bit and see what happens-stuff. |

Most active coders calls it line crunch (vertically) and VSP (horizontally) and the combination of the AGSP, and so should you. Sometimes you read DMA-delay for VSP aswell since that term is quite accurate on what's going on internally in the VIC-chip. |

Because VSP meant "variable screen position" from day #1: VSP&IK+ |
