Confrontation (1983)(M.C. Lothlorien) ROM

This is a turn-based wargame representing typical units of  mid 20th century armies.  Orders are given for each unit in turn and then the units move and engage with adjacent enemy units while the player watches.
The basic game allows creation of your own maps and battle scenarios, but there were also two sets of scenarios available as add-ons.  I remember the battle for Crete in 1941 being one of the scenarios, but the others have excaped my fading memory.  Was there an "Operation Sealion" scenario, or did I crete that one?  I cannot remember! 
There were limitations built-in, like Aircraft needing to land at an airfield after (I believe) 5 turns airborne.
It was not difficult to break the code and replace the icons for armies of earlier periods.
