Piracy

The more effective anti piracy method in Spain was to change the prize of the games from 2500 to 875 pesetas

Modifications to the standard Quick Disk format include the NINTENDO moulding along the bottom of each Disk Card.
In addition to branding the disk, this acts as a rudimentary form of copy protection - a device inside the drive bay contains raised protrusions which fit into their recessed counterparts, ostensibly ensuring that only official disks are used.
If a disk without these recessed areas is inserted, the protrusions cannot raise, and the system will not allow the game to be loaded.
This was combined with technical measures in the way data was stored on the disk to prevent users from physically swapping copied disk media into an official shell.
However, both of these measures were defeated by pirate game distributors; in particular, special disks with cutouts alongside simple devices to modify standard Quick Disks were produced to defeat the physical hardware check, enabling rampant piracy.
An advertisement containing a guide for a simple modification to a Quick Disk to allow its use with a Famicom Disk System was printed in at least one magazine.

Most Infocom games contained feelies, bonus novelty items included to enhance the immersiveness of the game. The feelies provided with this game included:

- A pin-on button with Dont Panic! printed in large, friendly letters
- A small plastic packet containing pocket fluff (a cottonball)
- Order for destruction of Arthur Dents house
- Order for destruction of Earth written in Vogon (actually an English cryptogram written in a thinly-disguised Greek alphabet. The text was nearly identical to that of the English Order for Destruction)
- Official Microscopic Space Fleet (an empty plastic bag)
- Peril Sensitive Sunglasses (a pair of opaque black cardboard sunglasses)
- How Many Times Has This Happened to You?, an advertising brochure for the fictional guidebook/encyclopedia The Hitchhikers Guide to the Galaxy
