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.

pernod, i noticed that on pouet ( http://www.pouet.net/prod.php?which=9801 ) it says that rutig banan was released at Pepsi Hacker Conference in august 1989, i guess this info comes from scenery http://exotica.fix.no/info/scenery/online/1989.html , was the demo shown there first, or is the information there simply inaccurate? |

@hollowman: the three last parts of Rutig Banan were finished in the summer of 89, and perhaps also shown to some people then (I can't remember), but they weren't released until november at Light's party in Bålsta.

How come my version of Rutig Banan only has the last 3 parts? I just checked the version in csdb, and it had 3 more parts than the version i have..
hehe.. btw, i distinctly remember checking out the code of part 4 (the shrinking Fairlight logo) and made the all border sprite zoomer I did in Design Overdose in kinda the same fashion (but easier code)...
hehehe.. routine ripping ahoy! I still cant believe i was the first one to make that, arent there any earlier examples? (Glasnosts all border zoomer is something else, imo). |

@Ben: where is the FLD in MegaJive? MegaJive2 seems to be older. In the CSDb the year is 1987. mhhh..
@XrAyZ: i would say the 'Edam Nibblers' (1001,scrolltext megajive) , spread the first fullscreen sprite pictures (ESCOS).

@Rost: Try wiggling joystick :) BTW.. Pressing reset also gives a nice 'stretcher' :) |

Just as an amendment to the FLI debate: X-Rated did the 160 (cheat) splits then in their party winner "Ratio 80". |

@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. |
