The BBC Micro conversion of Ultimate‘s classic Lunar Jetman is a very good one, using a high res display mode for the graphics, which are mostly monochrome (just like the Spectrum original).

It plays just as well as the original too, and this results in a very challenging, but very playable game. And let’s face it: the original is a very difficult game.

The task in hand: to collect a bomb and drive it to the enemy base, before picking it up and dropping it on an enemy missile launcher, is much easier said than done. Predominantly because there’s a time limit, and random alien sprites keep getting in the way, and holes in the ground impede your vehicle so must be covered with girders. Again: easier said than done. Completing the level by destroying the enemy base is possible (I’ve done it myself on occasion), which means doing it again at a higher difficulty level the next time.
