based on what Robert Munafo (the developer of the mapping tool) found out about the Eden file format (http://mrob.com/pub/...ile-format.html), I wrote my own program for reading Eden-files and manipulating them. I can change block types and colors (e.g. I could create a flat sand world or an ocean easily) and completely change the look of a world.
Mmy first manipulated world is Vuenccoaster 34min BOTTOMLESS where I removed all stone-, dirt- and grass-blocks that didn't neighbour on air or water. So I got this:
It's funny to see how all underground tunnels turned into "pipes"
The tool now runs relatively stable and doesn't consume too much RAM. It still takes some time to manipulate the world and you dont see the progress, so just wait when the program doesn't react.
The new version 0.2 now also contains a mapping tool, so I renamed this to "Vuenctools for Eden" (it's more than a manipulator now). You can make a map of the current world and save it to a png-file
Note that it's still not fully optimized, and further updates are coming.
How to get the world file:
You need iFunBox to load the file from your device to your computer. In iFunBox, open the Eden directory and open the Documents folder. You'll find some files with names like "kwahaldwmsnvnrezyebyrytudfenwyhdyayjdwdb.eden", now you need to find the world you're looking for. Maybe the preview pictures can help you, they have the same name as the world ("kwahaldwmsnvnrezyebyrytudfenwyhdyayjdwdb.eden.png"). When you have found the right file, copy it to your computer.
Start the world manipulator, open the file, manipulate it, save it (However don't try to overwrite the original file when saving, this will cause an error, but create a new one).
Then you can either replace the original file in iFunBox, or you copy the manipulated file into iFunBox with a new name (you'll have to restart Eden on your device to see the new world)
SOURCE CODE ON GITHUB:
This is still the old version, GitHub will be updated when 0.3 is released (further optimizations)
It's a Visual Studio C# project, in the readme.txt you find instructions for adding own manipulations
