A cruder version of this was created by the 1001 Crew already in 1986 by the name of ESCOS (Expanded Screen COnstruction Set). There's a video [1] and info page [2].
It was able to import images from KoalaPad, convert, and render it fullscreen using sprites both inside and outside the C64's border.
I will definitely take time to read the full article, it's super interesting at first glance.
Hmm, not really a cruder version of this. ESCOS is simply a wholy other trick, which also happens to be incompatible with this technique. As far as I know, it's not possible to open the side border while also performing FLI.
Not trying to downplay ESCOS - it was an important effect and release, foundational even. Just has nothing to do at all with FLI, NUFLI or now this NUFLIX variant, except that it was another nice and important timing-based VIC chip hack.
I love stuff like this! I have a Kaypro 2/84, which supports a display resolution of 160x100 with colors ranging from green, to 'less green' to black, and I went down a rabbit hole of trying to push the graphics: https://www.chrisfenton.com/exploring-kaypro-video-performan... - I was eventually able to get it do display (short!) 50 fps video clips.
I love this. The passion. The perfectionism. The complete absence of any commercial considerations. Just pure hacker culture, presented and disected with uncompromising attention to detail.
I also really appreciated the way this write up started with background information providing context for the uninitiated, and clearly laying out what the author set out to do and why. A crucial feature that's omitted far too often. Bravo.
