I wrote this many... many years ago. It is Battleships for the 48k Spectrum writtem in BASIC. Seen here running on WINUAE, so a PC emulating an Amiga, emulating a Spectrum! I could upload the listing if anyone is interested. Then you could type it into you Speccy, like we used to in the good old days from the computer magazines I actualy found a bug that I didn't know was there? See right at the end of the video. edit: BTW the way it's Zed eX Spectrum, it was made in the UK ...lol
