I have just made a new lake theatre with a 114 x 62 tile eaw32.tm file.
Because the tilemap is so small I was able to modify my tilemap viewer to show all of the tiles on screen, take a screendump and save it as a 24 bit BMP file
From the screendump I was able to create a "TargMap.PIC" and a "TargMap1.PIC"
It all works
Single mission selection:
Mission parameters
Inflight map
I was using the default tiles in the tilemap viewer, so I will have a shot at converting some nicer ones and making new mapscreens
