Side border scrolling
Here's a question that I've had on my mind for almost 20 years now.
How do you think side border scrolling was invented?
Do you think someone had sprites on the screen while a scroller was moving and they noticed a gap?
Perhaps someone was watching a depack routine and noticed that the side borders opened up by one raster line. You know the crunchers that used to increment $d016 as it uncrunched.
Or did someone simply break out the programmers reference guide and figure it out?
This is speculation but I'd like to hear your comments.
Oh and here's another... in the early 80's when there were no cartridges I always wondered how games were cracked. You would reset the computer by grounding the first and third pins on the far left port but you'd also lose data in the process sometimes. How would they have done it??? Granted much of it was simple disk error protection but it would still require you to reboot and load a monitor to view.
p.s. I think the easiest crack of all time had to be Flight Simulator in which, if you viewed the sectors it read "23 READ ERROR". You changed the 23 to a "00" (for OK) and it was cracked.

@rost:
Pre-FLD (sideborder in the middle with $d011 badline delay.)
4th of November 1986, Warlock, the intro to Highlander. Zyron and I are currently investigating whether this is Warlock or Warlock. |

Quoting zeusJust as an amendment to the FLI debate: X-Rated did the 160 (cheat) splits then in their party winner "Ratio 80".
What would that "cheat" be, fli ? |

AFAIK Mayhem in Monsterland uses VSP scrolling and there's at least the game Wizball which uses the upper/lower border as status display. |

Games using AGSP (VSP + linecrunching):
Fred's Back 1-3
Another World
An open upper/lower border is VERY common in games, usually the developers put a score display there (some examples: Paperboy, Warhawk, all SEUCK games etc etc).
Sideborder was used a few times, but usually only for a sideborderscroller in the title screen (Leviathan, Ben).
Also FLI has been used a few times. I remember the title picture of Clystron using hires FLI and I have a vague memory of some polish puzzle games using FLI in-game aswell.
I remember FLD being used on some koala loading pictures, and the title of Predator also uses it to make a text display look more interesting.
I'm pretty sure there is sprite stretching in games aswell. I guess only sprite crunching was never used in games, since it's use is very limited even for demos. |

Sould Crystal had only interlaced gfx in intro and ending.
Not during game itself.
IIRC it was MC-interlaced but I could be wrong |
