Having watched the 1943 arcade video - I realise that I need to add an enemy which travels in a diaganol direction and also enemies which loop the loop to return to the top of the screen.
Have found the following website which contains sprite images -
http://www.nes-snes-sprites.com/1943.html which is useful for helping with the overall layout of the sprite - although SEUCK won't allow you to import sprites.
