So, yesterday and this morning I redid the first level of the map for S3 Expedition to the Barrier Peaks for my personal use. I used GIMP 2.10.10. It was a lot easier than I'd thought it would be. The biggest hassle was setting up the grid to the proper proportion. Once that was done, the "snap to grid" feature made it really simple to lay down all the lines. Hopefully I got all the doors correct. I probably missed one or two.
Instead of letters for coding the color cards for the door locks, I used colors. Of course, gray and black didn't look good with the already black lines and gray shading for the lighting effects. So I switched them go green and blue.
