Haha, I'm just determined to do what I planned to do, which is being able to travel across the world of my own making, fight or talking with random creeps and finding secrete locations.
I tried something like this ages ago, but then I stopped when I heard it couldn't be done. As far as I can tell there have been people who have done it before and I intent, however hard it may be to succeed! I've been really inspired by chaos wizard's youtube tutorials and now I'm motivated to do map editor stuff.
@ Jojobobo
Thanks I'll give it a look
@ Drog Alt
You know now that I think of it, I might actually HAVE photoshop (the pay version though, not the stringy pete version

). Who knows, maybe I'll use both programs AT THE SAME TIME to do it! Nah that's crazy I'll pick one and stick with it
@ All
I don't mind as of yet how good quality the map looks, so long as it works. In a post from years ago, team a said you could export the terrain bitmap data, and rename it to map and Zoomed.bmp, tho he includes a WorldMap.mes which I don't understand all the parameters of it. Here's his versions of the mes files:
Rules/MapList.mes
{5000}{MainMap, 24201, 22819, Type: START_MAP, WorldMap: 0}
{5001}{ShopMap, 31, 29, Type: SHOPPING_MAP}
mes/gamearea.mes
{0}{0, 0, 0, 0 /A Place Unimportant/This is the unknown area.}
{1}{24291, 22860, -91, -1 /Nemorosa/A small mining town.}
{2}{23208, 20848, -70, -1 /Barton/A prosperous town.}
{3}{22293, 19926, -5, 0 /Port City/A large city.}
WorldMap/WorldMap.mes
{20}{50, 50}
{50}{1, 1, map, ZoomedName: Zoomed, MapKeyedTo: 1}
Edit:
At last! I have found someone's working module;
http://terra-arcanum.com/amtut/resources.htm (see comm_undat.zip at bottom).
Now I gotta find some way of getting mine to work using this. Still get those crashes when I click world map :S
