An einem blauen Tag

"An einem blauen Tag" – an adventure in monochrome

Released by HKÄP at Skrolli Party 2023

Duration: ~16 minutes

I started to experiment how to draw monochrome graphics in MS-DOS environment without any previous DOS development experience and ended up using a 32-bit compiler and virtual framebuffer. So we're certainly not talking about a historical accuracy of any sort. Goals of this product lie elsewhere in any case. During the project I nevertheless (re-)learned more about how actual monochrome animation was made back in the days before 32-bit processors. 

The video mode is CGA 4 (320x200). With actual monochrome display cards like Hercules I couldn't have chosen the color. There's also two color CGA mode but its resolution was more than what I needed.

Graphics engine is coded from the scratch. It uses my own bitmap image format (pbk - pakattu bittikartta). Also the drawing functions work at the bit level.

Enjoy
