A small bug was detected in Part I - Alexandria, when played on some ZX Spectrum Emulators for Windows;  ( not on Mac emulators ). 
So just to prevent this from happening no matter where you play, ( particularly of you´re going to play the game for the first time ), I recommend you download the NEW  "Chapter I - Alexandria ( enhanced ) REV.tap", I´ve posted now in my ECHOES OF ATLANTIS game page. 

The bug was not problematic to the gameplay and it only affected a descriptive bit in the story which is just there for atmosphere, but neverthelesss, it´s now corrected for this update.
