Crack Down Trivia (Amstrad CPC)
Amiga versionA mastering error on most copies of the Amiga version causes the final level to crash. A working version is preserved by the SPS project.
Copy protectionThe manual had got words from the game ("Dockyard, Atari, Bio-bot", ...) printed on each of the four edges of each page. The copy protection scheme asked questions from these words.
