NUFLI hardware scrolling
Let's say, I want to do line-cruncher with/or VSP with the NUFLI image...
what do you say? Possible or not? ;-)
Like an Dutch Breeze Elite FLI scroll but in NUFLI? Or just simple image moving.
I know Dane and HCL did a lot of XFLI movers in Tsunami etc. but that's software I guess. |

why wouldnt it be possible? i see no real technical reason at least (other than it might be more tricky to update the gfx in time than it already is with fli) you'll probably also have to design the image data in a way that it works out with all the colorsplits in sprite- and bg colors.
(and i somehow doubt the stuff in tsunami isnt using vsp =P) |

Yeah, I've checked – the first one uses memory rewrites, but the second one (with girls) uses some very clever tricks: line cruncher + VSP plus sprite shifting with line cruncher masking with white colour. Bizarre!
Probably the most complicated trick on C64 so far.
Check it out if you haven't seen Tsunami

It takes a lot of work to make something really difficult look effortless. Unfortunately, to the uneducated it will just look easy. ;)
My old ideas, made real by the divine intervention that is HCL. Well worth pixeling 4 screens of X-fli in the buggy editor.
And ofc NUFLI-linecrunching is possible. It would probably use the techniques from Tsunami - VSP, linecruncher and then jumping in/out to unrolled display code. The only problem you will face is of course hiding the sprite pointers gfx bugs that you get from linecrunching. With the X-fli mover we covered it up with neatly swapping gfx bank (and placing it in the white area) - haven't bothered to calculate if it's just as easy with NUFLI but I guess it can be done. |

Vertical movement (linecrunch) should be possible with NUFLI, but i doubt that horizontal movement (VSP) will ever be made. The NUFLI screen is very non-linear with the FLI-bug area and the rightmost char column.. Though a smaller picture not using full screen width should be possible to move horizontally. |
