is a split sideborder scroll done before??
high party people.
the last days i was bussy with coding a sideborder split scroll. with a split scroll i simply mean a scroll that scrolls the left 20 chars to the left and the right 20 chars to the right. through the sideborders... smooth ofcourse and i only used sprites in the sideborder, so no ugly extented graphics...
not very hard to code but i had some fun... the question i have is this done before and is there a record.. my version holds 25 chars high, and you only can use one speed... it scrolls the whole picture one pixel each frame...
i am curious.
greetings,
Testa

Well, 90% of those 1326 posts is nagging, nitpicking and about wishing back the old days =)
Yep, I'm an old sock. Hehehe :)
About the tunes: of course! |

Hey Testa, still don't know if you mean something like in this:
Happy New Year 2008

just a shitty 1x1-d016-split-borderscroller I did in 1993... definately your version sounds like pushing limits \ö/ |

yes Danzig something like that but i use another technique. .i ques you don't splitscroll any graphics at the bad line.. just a small charset 5 or 6 pixels high...
not the full 8 pixels so you can avoid badlines..
hint.. how do you want to split $d016 at the middle of the screen with openborders and 4 sprites at a badline??....
... wel you can't... still it is possible.. but i tell ya.. no splits at the badlines...

hmm really, what happens if one splits d016 in the middle of a line ? :) fex. fineshift=0 on the left side then 7 in the middle then simply d021 comes through where the screen is "teared appart" ? :) is this possible with d011 or one of the known d011 effects will come alive, or nothing? :) |

I expect x scrolling works much like y scrolling or the sideborders. That is the register value is used simply to determine when to start a process, in this case on which sub-cycle in the left border to start clocking pixels through the display shift register.
In other words I don't expect changing the x fine-scroll in the middle of a scanline to change anything. |

obviously this isnt a d016 split ;) but more like a rol/asl scroller. (it looks nice tho! :D) |

Ofcourse it does :( How else do you think Cruzer made those rocking highres arrows in the lower border + 8 sprites in One Year Camelot III? Or the 41 column wide picture Soundemon made in Tense Years? |
