A friend of mine has this but cant find any info on it anywhere, just a listing for the C64 version; http://www.retrogames.co.uk/more/on/details/014644
If anyone wants to take it off his hands or supply further info, drop him a mail at microsproutAThotmailDOTcom
Just had a word with the seller and its basically a tape copier, theres a few options etc to choose from and he just managed to make a prefect copy of Phantom Attack, so at least it does what it says. Cassette only and all instructions are within the program.
