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.

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.

as someone who learned coding on a c64 back in 80s

speechless. this is just great

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.
