|The tape will crash if you don't have BASIC (revision A) either as a real cartridge in your Atari or attached as an image in your emulator (for users of XL or XE machines, make sure built-in BASIC is disabled and computer is set to PAL mode). You can get the ROM here.|
If you are using a real system, the cassette will boot by holding down START, powering on and pressing any key at the beep. The game will simply auto-load on standard emulators.
Note that the three games need to be loaded separately. After the first and second parts, press RESET, type CLOAD and RUN.
Many thanks to AbbotKinneyDude and Daniel Coulom of http://dcmoto.free.fr/ for the scans and tape dump!
