You could play the adventure until you found the time travel machine (could take 1 to 3 hours depending).
You start the machine and then it went on infinite loop text : "tired of piracy tired of piracy tired of piracy..." !
Highly frustrating, but you couldn't help to admire the developper.
If I remember correctly, it was something about the way that a floppy track was formated, with the wrong number of sectors, which was readable by the disk drive, but it couldn't write it using normal copy mode.
