Petscii Robots Modern Map Editor

[sol1013]

I really like the game! As far as I know, there's only a map editor available for the PET version. I was a bit bored, so I ended up reverse-engineering the level structure to some extent and eventually managed to display the map using the attached Python script. It only requires PyQt5 as an external module.
I got the tiles from the Amiga version on GitHub, and the levels from the PET version (also from GitHub). The tiles (or all bitmaps needed) need to be placed in a folder named "tiles" in the same directory as the script. Before loading a level (map), rename it level.bin and set the tiles (after starting the script) to something that starts with "tiles". You can edit by choosing a tile on the right side, undo (Ctrl + z) is also possible.
That said, it's just a small script, and my knowledge of both the level file structure and Python Qt is pretty limited. For example, editing a map and saving the result currently corrupts the level. But maybe someone out there knows exactly what each byte in the level file does — and how to implement robots, objects, and everything else...

Nice, makes me wonder what David himself used to create the maps

Thanks! As far as I know, he used the PET, and all the maps are from it.

Big update: I checked the PET code and found some useful information about the positions of the robots, doors, hidden items, etc., which are now displayed (though not too detailed). It’s still not a map editor by any means, but for now, it's a cheat map creator.

Okay, I’ve made some more changes and restructured the code.
I’ve also set up a GitHub repository here:

Any help or feedback is welcome!

Big update: Map and unit editing are now possible (note the water raft and the extra robot in the first screenshot)! While there may still be bugs and the UI might need improvement (code is also not well-structured), feel free to give it a try if you're interested. Check the map data offsets (can be changed in constants.py), it might be different in your version.
