Things C64 coded by LDX#40 (page on CSDb).

An emulator such as VICE is needed to view this stuff. Or the files can be transferred to old 5 1/4" disks for use with an original C64...

Off the Grid (2021) [Download] .d64, 20 KB

Old-school demo, PAL only. Can you find the super secret disco epilepsy mode?

Created over 10 months (with breaks). A massive learning experience for all things raster-interrupty.
Major pain in the butt: getting the raster lines in the border to display properly with all those sprites flying around.
Had a lot of fun creating a pure C64 track again. Also fun & illuminating: reverse engineering the music player my sound software uses.

You can watch the full demo on vimeo.

PVG (2019) [Download] .d64 & manual as text file, 18 KB

The PETSCII Video Generator (PVG) generates patterns based on the C64's native character set. The user can control the drawing algorithm, the set of characters used, the color scheme, and many other options during runtime. Alternatively, there is the randomize mode which hands control over to the machine.

Originally created as a tool to provide video for live shows. Makes also for an excellent screen saver, abstract digital aquarium or hallucination trigger.

Be sure to check out the instructions provided in the program (press F1 in the screen where you enter the time). And yet again there's a hidden feature...
