In fact, I AM using the original disc(s). I bought the game as soon as it came into stores. And I do have the Map Editor 'inside' the game program. It's not a Steam version or downloaded in any other way.
I just thought I saw a downloadable Map EDITOR on the site but instead, it was the Map BUILDER.
I downloaded the BMP2GMP program twice, from Hawk & Badger and Molse's Downloadzentrum (http://dl.railroadtycoons.de/index.htm
). I used used both of them to 'paint' the map but they gave the same results. Which leads me to think there is some sort of bug in my Map Editor.
The strange thing is though, when I opened the maps Wolverine posted here they were just fine.
I would really like to have a solution to this so I can create maps using images on my own, instead of asking other people to do it for me...
I am looking all over the place for a solution but so far I haven't found anything yet.
