I've just unearthed, tidied up and re-released a utility I wrote almost ten years ago to modify the Electron version of Micro Power's Moon Raider.
Sometime in the 1980s, my brother and I happened to discover that, after pressing Break, you could restart the game by simply doing a "CALL &1900" from BASIC. We then went looking for the map data in memory and found it at &5000-&5700.
Sometime later, I wrote the MoonMap tool to patch a UEF file with new level data:

The repository containing the sources and some sample level maps can be found here:
