Yeep!Eep!Eep! (2010)

Yeep!Eep!Eep!Program (or YEEP) creates images reminiscent of computer error using the unique retro pseudographics of the Commodore 64. By manipulating the VIC registers, YEEP generates images based on data that happens to be in RAM at the time, and what was on the screen just before the program ran. This information is mediated through character sets controlled by the user. It also has controls to alter the color and add additional data to be drawn. The entire palette available on the C64 is in use (all 16 colors!).

To run, use VICE or another C64 emulator.

Download YEEP as a disk image. The name of the program is "YEEP01". If you're using drive 8 (in VICE, for instance), type:

I STILL have a few (at this point, <20 ) copies remaining of my book of images from YEEP (edition of 100). See images on my blog or on Ruins & Books. I have more copies of my second edition, which is prettier, but not hand-made (it's also an edition of 100), email me for more info.
