Open Pilantra is a cinematic random story generator that started its days when I was messing around with semigraphics 4 on this thread: viewtopic.php?t=6
It is now available for download + source at: https://fued.net/
Available disks for English and Portuguese, the source is for the English version and the code has comments all around (some weird ones too).
It comes with a PDF describing the project and its techniques as well as a little tutorial on how to get ugBasic and Xroar (coco emulator) up and running, I will bring that tutorial up viewtopic.php?t=198.
