Richard Gadd has made a version fixed with a patched MasterDOS so they work with just 1Mb in slot 1. They have also been converted to work on B-DOS and with just 256Kb.
If external memory and (fixed) MasterDOS are detected all files are loaded into and then retrieved from RAM disk when needed for extra speed.
All other memory configurations and/or non-MasterDOS combinations will pre-load the required files for the Wizard part and the "screen manipulation" part except for the Astronaut screen manipulation which for 256Kb users will be streamed direct from disk.
The Wizard graphics are from introduction sequence of the Atari ST game Wizball.
