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:


LOAD "YEEP01",8
RUN


Also see the post on getting started with YEEP on my blog (contains more screenshots from the program)


I have copies remaining of my book of images from YEEP. See more on my blog or email me for more info.

v0.1 is written in Commodore BASIC 2.0. Future versions to follow, bringing more glitchiness to the display, and less to the program functionality.
