Hi TED editor is the terrain editor for redbaron it is a very old piece of software. 1996. you can run it, but it needs something close to 1996. on windows 7 , this worked for me : 1 ) put your screen in an old fashioned mode. 1280x960 or 1280x1024 worked for me. anything bigger crashes TED.exe 2) put it in 256 bit color. again, if you do not, it crashes on trying to display the baronX.ted map 3 ) the scale for the redbaron maps (flanders, as example ) displayed can be set: click menu->edit => World Scale. It is approx 27 meters (or 88 ft for the non-metric anglo's ) per "Grid file unit"; what is that ? right. The length / width of a ted is 16 blocks (real maps, not the island. island is smaller) block. One block is covered by 16x16 bitmaps (the size of this level 3 bitmap is 256x256 pixels). One pixel is 64x64 coordinate unit = the level 3 bitmap is the Grid file unit. So: ted lenght=16(block)x16(bitmap)x256(pixel)x64(unit)= 4,194,304. Anyway, using that scale gives you 156 kilometers by 156 kilometers, which is the correct size for the redbaron maps (excluding island ) One single level 3 tile is then approx 300 meters, which is about right ( a thousand feet )
