The game uses Essential Myth's GACPAC; which they later made available for Spectrum users.
The original Amstrad CPC released by CRL, archived in many places online, was seriously bugged; starting the player off in the wrong location. This was eventually fixed and a free replacement was offered by indie-publisher Recreation Re-Creation when they later republished the game. A bug-fixed version of the game, utilising their revised "part 1" can be downloaded via NVG.
